Bug ID: 493657
Summary: Cursor laggy
Classification: Plasma
Product: kwin
Version: git-stable-Plasma/6.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
After updating to Plasma 6.2, I noticed that the cursor is laggy on the desktop
and in the settings. After that, I opened Firefox, it was okay there. Opened
Brave browser and cursor was laggy there as well (regardless if run in Wayland
or X11 mode). I'm not sure what the pattern is.
This only happens if VRR is set to always.
Didn't have this issue on Plasma 6.1.
Happens both on main laptop and on external monitor (both run in 60+ fps).
STEPS TO REPRODUCE
1. Have VRR set to Always.
2. Open settings.
3. Move cursor.
OBSERVED RESULT
Cursor is laggy. Opened a fps online tester in Brave browser, it was actually
running in 120 fps, only the cursor was laggy.

drops to normal size.
