Created attachment 172413 [details] example of the graphical corruption *** If you're not sure this is actually a bug, instead post about it at https://discuss.kde.org If you're reporting a crash, attach a backtrace with debug symbols; see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** SUMMARY When using KDE Plasma with Wayland session and 3 4k screens (125% scale) there's occasional graphical corruption on chromium based applications. The corruption manifests as images on webpages getting an "aurora borealis effect", missing text or flashing colours. Hovering the affected areas will usually make the window refresh and render properly. The corruption is visible to screen recording software. STEPS TO REPRODUCE 1. Use system normally. OBSERVED RESULT Occasional Corruption EXPECTED RESULT No Corruption SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora Linux 40 KDE Plasma Version: 6.1.3 KDE Frameworks Version: 6.4.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION Lenovo Thinkpad P1 Gen 7 with Intel Ultra 7 165H Arc iGPU only through Lenovo Thinkpad Workstation Thunderbolt 4 Dock for 3 4k Screens
I've since then experienced corruption when not using multi monitor, so multimonitor is not related.
Can you confirm if Chromium is running in wayland mode nor not? An easy test is to run "xprop" and hover over chromium. If the cursor changes to "+" shape, it's in Xwayland. If it is in wayland, and it's the only application with corruption please report there. Arc GPUs are new and Chromium's wayland implementation is new.

Arc GPUs are new and Chromium's wayland implementation is new. I believe it happens both on native and xWayland sessions, been a while so would have to test a again to confirm.
I've confirmed that it does happen in xWayland (default) and Native Wayland sessions.
