Disabling dynamic wallpaper video rendering loops, switching to static backgrounds, and clearing Dock expose caches.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

  1. Switch all desktop spaces to static wallpapers in System Settings > Wallpaper.
  2. Flush compositor memory: sudo purge && killall Dock.
  3. In Desktop & Dock, change ‘Click wallpaper to reveal desktop’ to Only in Stage Manager.

Following this procedure restores full stability with zero recurring log errors.
