Created attachment 482003 [details] Arrows point to strange, coloured backgrounds behind the app icons when I alt-tab Description of problem: The application icons looked normal at first but, after a few hours of use, they render "strangely" with "colourful" backgrounds. This is noticeable in both the Overlay Mode's Applications tab and when using Alt-Tab to switch. Version-Release number of selected component (if applicable): gnome-shell-2.91.90-2.fc15.x86_64 How reproducible: Only just started happening. Steps to Reproduce: 1. Started to happen after using GNOME-Shell for a while. 2. 3. Actual results: Application icons changed appearance. Expected results: Should stay the same. Additional info: See screenshot.
