Release History

Next version (not released yet)

Bug fixes

• Fixed the error “Unknown wallpaper type: 23” when opening “Wallpaper effects” for a monitor that plays a frame-sequence animation (a BXAnimate_ folder). Such a monitor also did not restart its animation when BioniX started. Both work now.
• In “Wallpaper effects”, just clicking another effect in the list stopped the effect that was running, and Cancel then left the monitor on the last effect you clicked, stopped. Now the monitor changes only when you press OK or Apply, or open the settings of an effect.
• Fixed the OK button of “Wallpaper effects” hidden under the Windows taskbar on a screen 768 pixels high. The dialog was taller than the screen. It now has two columns and fits.
• Fixed: in the About box, the “Remaining time” line and the build information line were drawn over each other. Each now has its own row.
• Fixed a deleted animated GIF or WebP that went on playing. When you deleted the animation that was on screen, it kept playing, and with no GIF left in the playlist the warning “No GIF files found!” never appeared. Deleting it now stops it.
• Fixed the Slideshow and Photo Pile countdown not running after BioniX was restarted, so the wallpaper did not change by itself. The countdown now starts again with the effect.
• Fixed the error “The process cannot access the file because it is being used by another process” for a thumbnail at start-up. The playlist tried to read a new thumbnail while it was still being written, and its cell stayed empty for a moment. A thumbnail now becomes visible only when it is complete.
• Fixed a memory fault that could crash BioniX at a random moment after it made thumbnails in the background (while resizing an image, drawing a placeholder thumbnail or reading a GIF).
• Fixed: an image smaller than 12 pixels on one side could still crash the beta builds while its thumbnail was made, through a path that the v15.30 fix did not cover. Such images are now resized like any other.
• AI border fill: after a change of screen resolution, a border that was waiting in the queue was drawn at the old size. On a smaller resolution the picture spilled past the edge of the monitor, and the next wallpapers on that monitor had the wrong size too. The border is now drawn at the current size of the monitor.
• AI border fill: when a monitor moved on to the next wallpaper while its AI job was still waiting in the queue, the border made for the old wallpaper could be painted over the new one. Such a job is now dropped.
• Shader effects such as Starfield now use the graphics card. A wrong setting had made all of them fall back to the processor, which is many times slower.
• Starfield: the stars jumped to a new place when the mouse moved, and the whole star field changed when you changed a setting. The mouse now turns only the view, smoothly.
• Panic: on a monitor that showed Photo Pile, the panic image did not appear. The panic image also counted as a played wallpaper and went into the wallpaper history, where “Previous” could later crash BioniX. The panic image now appears on Photo Pile too and leaves nothing in the history. Panic also hid the control strip of every mini-monitor for good; it comes back now.
• The wallpaper properties window no longer stays on top of every other program.
• Fixed: for some users no tooltip appeared anywhere in BioniX, and ticking “Show hints as tooltips” did not bring them back. The checkbox works now. After the update the tooltips are on for everyone; if you had switched them off, switch them off once more.
• Fixed: the folder for internal files (Settings, System) was ignored for thumbnails. They were still saved in the default folder.
• Licence: after the licence key was uninstalled, the next start of BioniX ended with an error. BioniX now starts normally, in demo mode. Licence errors now also appear in the BioniX log.
• Fixed “System Error. Code: 1400” (invalid window handle) when applying a video wallpaper. If Windows Explorer had restarted in the meantime — or the desktop theme had been changed from the Personalize menu — Windows destroyed the hidden window BioniX paints wallpapers on, and BioniX kept trying to use it. BioniX now notices that the desktop was rebuilt, re-attaches itself to it automatically and repaints the current wallpaper. Before this fix the wallpaper silently stopped updating after an Explorer restart.
• Fixed “No monitors detected!” appearing on every wallpaper change after a screen-resolution change. If anything went wrong while BioniX was rebuilding its monitor list, the rebuild stopped halfway and left the program with no monitors at all until it was restarted. The rebuild now survives a failure on a single monitor, and it never throws away the monitors it already has unless it can really build new ones.
• Fixed a crash when restoring BioniX from the tray after one or more screen-resolution changes. Every resolution change left an invisible, orphaned copy of a mini-monitor panel behind, still pointing at data that had already been released. Those leftovers are now released together with the monitor they belong to — which also removes a small memory leak on each resolution change.
• Fixed: “Test connection” and “Refresh” in the AI settings could freeze BioniX for good.
• Fixed several crashes: deleting a wallpaper while its thumbnail was being made; sorting or cleaning the playlist after the window was made wider; a screen-resolution change after wallpapers were deleted from the playlist; the URL checker; closing the AlphaCoders browser (which also froze for 5 seconds); a Parallax layer saved as an 8-bit PNG.
• Fixed the error “Hidden monitor can only have efNone plugin” in Expand mode when “Previous” or another command for the primary monitor was used, and an error box on every resize of the main window after a failed monitor rebuild.
• Playlist files are safer: a failed save no longer empties your playlist file (BioniX now writes a temporary copy first), and a damaged or locked playlist file no longer wipes the playlist that is open or the “last playlist” setting.
• “Move to category” overwrote a file with the same name in the category folder, then deleted the original. The moved file now gets a free name (for example beach_001.jpg).
• “Clean orphan thumbs” deleted the thumbnails of playlists saved outside the BioniX data folder, and deleting one item erased the thumbnail that its duplicate still used.
• Effects no longer stop or change by themselves: the slideshow froze after a change of span style; opening a playlist stopped the effect on every monitor; Photo Pile froze after its first pile and became Slideshow at every restart; waking from sleep replaced every animated effect with Slideshow and saved that.
• Unplugging a monitor no longer changes your saved span style (Clone or Expand) to Individual. In Clone mode, pausing the countdown on one monitor no longer restarts it on the others.
• Settings that were lost: opening the settings of a shader effect reset all its values to the minimum (and OK saved them); the thumbnail height and “Show thumbnails” were erased at every start; Day/Night and “Time in file name” overwrote your countdown interval; a new install saved empty AI prompts.
• AI border fill with ComfyUI: a generation without upscaling never finished. Changing the prompt, the model or the picture now makes a new border instead of reusing the old one. Turning AI off stops the running job, typing in the server box no longer restarts everything, and BioniX no longer leaves two full-size images on the ComfyUI server for every border.
• Playlist > Advanced > “Generate thumbnails” did nothing, and the playlist showed one more column than fits, which hid the right-hand thumbnails behind a scroll bar.
• First run: the wallpapers added in the intro wizard were wiped. Opening with BioniX an image that was already in the playlist applied a different wallpaper.
• “Add images from folder” skipped the WebP images in the folder, and the “Add single image” dialog did not list WebP files. Both find WebP files now.
• “Animated wallpaper (video)” chosen in “Wallpaper effects” never played the video. Parallax: red and blue were swapped on 24-bit layers, and a layer with drift slid off the screen.
• The calendar, text, hardware and particle overlay settings can be opened from the main menu. “Reset settings” no longer leaves the taskbar or the desktop icons hidden. A wallpaper named for midnight (00-00) is now used in “Time in file name” mode. Running the URL checker twice no longer marks every URL as invalid.
• Playlist: thumbnails that could not be made are tried again when you change the thumbnail size.
• Parallax: a layer saved as a 4-colour PNG was drawn as stripes of the wrong colours.
• Parallax: a new layer folder chosen in the Parallax settings is now shown at once, also while Parallax is running.
• The small monitor preview in the main window now shows the message of a blanked monitor (for example “<BioniX Wallpaper>”), not just a black picture.
• The AlphaCoders browser could stop working when Windows had been running for more than 49 days without a restart.
• “Add URLs”: the button that shows the advanced options shows a gear again, not a wrong letter.
• Countdown settings: the Stop button showed the Pause symbol.

Changes

• Starfield: the stars no longer always slide from right to left. They fly out of the centre of the screen toward you, and the mouse turns the view.
• Starfield: new “Mouse sensitivity” setting (0 to 200%, default 70%) for how far the mouse turns the view.
• The buttons on the bar under each small monitor preview are flat now, all the same size and centred. The countdown ring no longer sticks out of the bar.

v15.44

• Maintenance build: extra error handling in the AI settings (“Test connection” and “Refresh”), which now show an error in the dialog instead of failing silently.

v15.37

Bug fixes

• Fixed access violation in TMainMenuBarStyleHook.Invalidate after changing a skin and then clicking the main menu. Caused by a long-standing Delphi VCL bug: SetStyle leaks the previous skin’s menu hook, and the next main-menu click reads freed memory. BioniX now persists the chosen skin to its settings file and asks the user to close and reopen the app, so no live SetStyle is issued while a menu hook is alive. Same approach HeidiSQL adopted for the same VCL bug.
• Fixed the long-standing “EAssertionFailed: No file was open yet!” crash that could fire when starting an animated video (AVI / MP4 / etc.) wallpaper if the FFmpeg libraries failed to load or the file no longer existed. The animation plugin now resets its state cleanly on failure so reopening the dialog and clicking OK no longer hits the assertion.
• Hardened the same family of failure paths in the animated-GIF and animated-WebP plugins (they would have looped retrying a corrupt file). The createAnimPlugin orchestrator also now checks the load result before starting the animation instead of starting it blindly.

v15.36

Bug fixes

• Fixed startup error “The png image could not be loaded from the resource ID” on Windows 11 24H2. The countdown spinner’s frame resources were missing from the patched LightSaber VCL unit, so the load raised inside the plugin constructor. Restored the resource and the spinner animates cleanly again.
• Fixed shutdown assertion (“TBXMonitorEx — Plugin cannot be Nil!”) that fired when the above startup error had left a per-monitor plugin uninitialized. The destructor now skips the LastPlugin INI write when the plugin never came up, so a startup failure no longer turns into a second crash on close.
• Fixed cosmetic bug in the Log window where the “Time” and “Message” column headers were drawn twice with a slight offset, producing a ghost overlap under VCL skins. The custom paint path now defers to the grid’s default header rendering.
• Demoted the noisy “Saved path not found in playlist” warning during early startup (when the playlist hasn’t been loaded yet and the first call is always expected to miss) from a red warning to a verbose hint.

v15.34 (Beta)

Bug fixes

• Fixed crash (“getCursorPos: Playlist is empty”) when the per-monitor countdown ticked while the playlist was empty — typically while the EULA / intro / skin chooser was still showing on first run. The countdown now stops cleanly instead of raising; the playlist’s Next-wallpaper helpers also short-circuit on an empty playlist.

v15.33

Bug fixes

• Near-instant startup — the slideshow fade animation was running on the very first wallpaper apply at boot, blocking the main thread for ~4 seconds per monitor (8 s+ on dual-monitor setups). The fade was invisible anyway because BioniX was fading from the host window's blank initial state to the same wallpaper already on the Windows desktop. The startup path now skips the fade.
• Fixed crash (“Hidden monitor can only have efNone plugin”) when opening the Effects picker on a monitor that is hidden by the current span mode — physical monitor in Expand mode, or the virtual expanded monitor in Clone/Individual mode. The picker now shows a friendly explanation and exits cleanly instead of letting the user pick an effect that the engine cannot apply.
• Fixed crash (assertion failure in the Effects picker) when pressing Enter while the OK button was disabled — e.g. with an empty playlist. The Enter handler was bypassing the disabled state and tripping an internal check. It now exits gracefully.
• Fixed latent crash when applying a video to one monitor while another (currently hidden by the span mode) still carried a stale video-plugin state from before a span-mode change. The video hand-over routine now correctly handles hidden monitors instead of trying to switch them to slideshow.
• Fixed shutdown crash (Access violation in System.Net.HttpClient) when closing BioniX while an online wallpaper download was still in flight. Pending downloads now drain cleanly before the playlist is freed, so the worker thread never runs into a half-finalized program.

v15.32

Bug fixes

• Fixed Stability AI cloud provider — outpaint requests were malformed (sent a mask instead of the directional pixel padding the endpoint expects), so nothing reached the server. BioniX now sends the original image plus the correct left / right / up / down padding values.
• AI completion callbacks now pin to the main thread's Synchronize queue, eliminating a theoretical race where a result could be dropped if the worker thread terminated first.

v15.31

Bug fixes

• Fixed thumbnail generation (multithreading issues)

v15.30

• AI-powered wallpaper border fill — automatically extends wallpaper edges using local AI (ComfyUI) to seamlessly fill any monitor aspect ratio
• Support for both local (ComfyUI) and online AI providers
• AI batch processor for processing entire wallpaper collections across multiple monitors

Bug fixes

• Fixed FadeBorder crash (“wallpaper is larger than the desktop!”) when image aspect ratio matches the monitor — added downscale guard for oversized wallpapers
• Fixed crash (EAssertionFailed) in StretchF when loading very small thumbnails (less than 12 pixels in any dimension)
• Fixed EAccessViolation crash during application shutdown (Embarcadero bug workaround in Vcl.WinXCtrls)

v15.23

Bug fixes

• Fixed crash with GIF files

v15.22

Bug fixes

• Fixed crash (EAccessViolation) when closing BioniX after using the Parallax effect
