Bug 511823

SUMMARY

After upgrading from Plasma 6.4.5 to 6.5.2, any event that changes mouse cursor results in cursor lag: when hovering over the button (which changes regular cursor to the hand with the finger), the cursor is freezed for several milliseconds (not moving), and only then it is positioned to where it has been moved with the new icon.

This usually happens only first several times, after which the lag is gone for some time.

STEPS TO REPRODUCE
1. Run Plasma 6.5.2 on Fedora 43
2. Hover over any element which changes mouse cursor in any software
3. Get the cursor lag

OBSERVED RESULT

Visible lag (absent of mouse movement) of several milliseconds when hovering over mouse-icon-changing elements.


EXPECTED RESULT

No visible lag, as it was in Plasma 6.4
