Bug ID: 433554 Summary: Visual artifacts on monitor that uses 100% scale when using custom (both fractional and integer) scaling on a second monitor. Product: kwin Version: 5.21.1 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: multi-screen Assignee: kwin-bugs-n...@kde.org Reporter: ricardo.steij...@gmail.com Target Milestone: --- SUMMARY Visual artifacts on monitor that uses 100% scale when using custom (both fractional and integer) scaling on a second monitor. Everything does look fine on the second monitor though. STEPS TO REPRODUCE 1. Have a multi monitor setup (tested on 2 monitors) 2. Set 1 monitor to a custom scale (150% and 200% were tested so far), 1 monitor to 100% 3. Open the setting app, check the fonts (tested with various fonts) 4. Hover the mouse pointer over the window decoration. It should look distorted (tested with Adwaita, Capitaine & WhiteSur cursor themes) 5. Right click on the desktop on the 100% scale monitor and hover over the submenus. Some areas should go transparent/flicker for no reason. (tested with Breeze-dark and WhiteSur themes) 6. Clicking in the topbar sometimes doesn't show anything or go transparent/flicker. (tested with latte-dock-git r5033 & Plasma panels) OBSERVED RESULT See reproduce steps above. EXPECTED RESULT Everything on the monitor that's running on 100% scale next to a monitor with custom scale, should look exactly the same as it would normally, without a custom scaled monitor or without a second monitor at all.
