Bug ID: 473451
Summary: On X11, the mouse cursor, when switching states, tends
to glitch
Classification: Plasma
Product: kwin
Version: unspecified
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: unixst...@protonmail.com
Target Milestone: ---
SUMMARY
In essence, the bug is exactly the same as
https://bugs.kde.org/show_bug.cgi?id=447797, but now it appears as if it
happens on X11 as well, where it used to only on Wayland.
Whenever the mouse cursor has to switch the state (when inputting text,
selecting, etc.) it temporarily glitches out – moves slightly to the side and
looks as if it has some kind of tearing.
It would be nice, visually, even if this is an upstream bug, for there to be a
workaround.
STEPS TO REPRODUCE
1. Switch to X11 session
2. Move the cursor over any object in any application which has to change the
state
OBSERVED RESULT
The cursor moves in one direction and experiences visual tearing while
switching states.
EXPECTED RESULT
The cursor state should smoothly change, without tearing.
SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
I'm using Mesa on an Intel iGPU. I haven't tried to use the Nvidia card for the
