Wallper v1.6.3

Smart Sync — Dual player support & reliability fixes

New Features

Dual Player Support

• Apple Music and Spotify can now play simultaneously with seamless switching
• When one player pauses, wallpaper and lockscreen automatically switch to the other active player
• When both players are paused, original wallpaper and lockscreen are restored
• Active player state tracked in real-time via system notifications

Desktop Background for Music (macOS 14–15)

• On macOS versions without lockscreen API, music gradient is applied as a desktop wallpaper
• High-resolution 4K gradient image rendered from album colors
• Toggle in Settings → Music Sync: "Apply to Desktop Background"
• Original desktop wallpapers saved and restored when music stops
• WallpaperAgent restarted after applying to ensure immediate visual update

Improvements

Lockscreen Caching

• Lockscreen video is no longer re-encoded when an identical file already exists in cache
• Cache checked before downloading remote files - skips unnecessary network requests
• Three-tier install pipeline: fast-path (same video) → cache-path (transcoded file cached) → slow-path (full download + transcode)

Music Sync Reliability

• Debounced pause handling (400ms) prevents rapid Paused→Playing flickers from causing cascading lockscreen renders
• Pending lockscreen render tasks are cancelled when restoring original wallpaper - eliminates race condition where a late render overwrites the restored lockscreen
• Previous lockscreen URL correctly saved - music-reactive files are never stored as "original" lockscreen

My Media

• Liked videos now appear immediately when opening My Media (previously required a new like action to load)
• Video preview thumbnails load reliably - fixed race condition where async preview generation didn't trigger image reload

Bug Fixes

• Fixed lockscreen not restoring to original wallpaper when all music players are paused
• Fixed multi-monitor wallpaper save/restore - each screen's wallpaper is tracked and restored individually
• Fixed "other player still playing" false positives caused by stale AppleScript state
• Fixed preview thumbnails showing placeholder 50% of the time in list view
• Fixed liked videos list being empty until a new like/unlike action was performed
