SUMMARY Cursor appears to be rendered at 60Hz when using a high refresh rate display (144Hz) when using Plasma 6.0 Beta 1 in Wayland. STEPS TO REPRODUCE 1. Launch plasma-wayland-session with a high refresh rate display 2. Observe cursor movement OBSERVED RESULT Cursor movement at 60Hz. EXPECTED RESULT Smooth cursor movement at 144Hz. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 5.90.0-3 KDE Frameworks Version: 5.246.0 Qt Version: 6.6.1 ADDITIONAL INFORMATION Possibly related to mixed refresh rate multi-monitor (144Hz and 60Hz monitors), will update with more information.
What hardware is this on? Also, please attach ~/.config/kwinoutputconfig.json
Created attachment 164262 [details] KWin Output Config CPU: Ryzen 5700x / 32GB RAM GPU: Radeon 6800xt Mouse: Logitech GPX I should've added that cursor movement can be smooth when an application is maximised (I've been able to replicate this with Firefox so far, not with KDE applications) but when the cursor moves over the desktop it can lag. Let me know if you need any more info :)
Ah, your problem is caused by https://gitlab.freedesktop.org/drm/amd/-/issues/3034. Turning adaptive sync down to automatic should be a viable workaround for now
