Hi, i’m using two monitors with my laptop. The first one (larger one) is set to 75% scaling, while the secondary monitor uses 100% scaling, and since chromium made wayland the default ozone platform (chromium 141) browser scales down itself every mouse interaction in the first display (75% scaling), it seems like the issue occurs only when scale is set below 1.0 (browser works fine when scale is set to 100%), the issue affect every chromium based apps. However setting chromium flag “–ozone-platform=x11” makes browser works fine.
