SUMMARY AMD 7700X IGPU does not fully function as a secondary monitor source under Plasma Wayland but does work in GNOME and other wayland desktop environments. STEPS TO REPRODUCE 1. Connect the iGPU to a external DP monitor. (1440p used) 2. Log into Plasma Wayland and setup multi display configuration and APU IGPU as secondary. 3. Drag mouse cursor or windows into iGPU Display space to see issue(s) OBSERVED RESULT The desktop connected to the iGPU will have no cursor and produce odd artifacts but otherwise will let user drag a window onto it and even watch video correctly, but you will notice odd artifacts and delays when doing so. EXPECTED RESULT No artifacts when dragging windows around and mouse cursor rendering correctly. SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.5.8-zen (available in About System) KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.111.0 Qt Version: 5.15.11 ADDITIONAL INFORMATION This issue has persisted for quite some time, possibly since Zen4 launch. It has existed over many KDE Plasma versions and has yet to be fixed nor have I found any real direct solutions or workaround for this particular issue. Changing refresh rates on any/all displays does not fix the issue. Unable to disable primary display to test iGPU out by itself, it just resets to multi display config. Possibly its triggered by the primary gpu being on HDMI and the iGPU being on DP? Happy to produce logs on request, unsure which ones would be useful atm.
Please attach the output of drm_info here. Multi gpu has been entirely reworked for Plasma 6, so if you could test the beta or rc1 that could be useful as well - this might already be fixed

This out again, since this was a issue I moved the display output all to the main GPU. I will move it back and retest this issue, however my main GPU has changed from a 7900XTX to 4090 so hopefully that doesn't affect outcome.
