Research direction

The payload names no files, so start by reproducing it: run Wayfire with the wf-background plugin set to rotate the wallpaper every 30 seconds, then activate Expo and watch the desktop previews as the wallpaper changes. The report says only the active desktop's preview updates, so the work is to find where Expo caches or renders the background for the other workspaces. Done means every desktop preview shows the current wallpaper while Expo is open.
