Created attachment 161054 [details] Video showing menu issue SUMMARY Fractional scaling causes menu flashing/tearing as the mouse moves over the menu entries. It's almost as if the menu is being raised over itself on highlighted segment at a time. STEPS TO REPRODUCE 1. Use Wayland 2. Use one 1440p monitor, one 2160p monitor 3. Set the 2160p to 150% scaling 4. Right-click on desktop, move cursor over menu OBSERVED RESULT See attached video for better description than I can provide with words. When pressing Print Screen to open Spectacle to take a static image, the areas the mouse has not moved over vanish, leaving holes in the menu (the windows below it are shown). EXPECTED RESULT Behaviour like with no fractional scaling - no flashing, no holes in the menu etcetera.
