Release History

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
• AI settings panel with provider configuration

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
• Fixed error when loading monitor frame PNG on systems with restricted folder permissions (e.g. installed under C:\BioniX\)

• Fixed crash after applying skins
• Fixed cursor not properly drawn when not in Thumbnail mode
• Fixed crash when generating thumbnails (multithreading) — “File locked by other process”
