Bug ID: 478454
Summary: Flickering and glitchy mouse cursor in X11 session
(when compositor is on)
Classification: Plasma
Product: kwin
Version: 5.27.5
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org

Target Milestone: ---
SUMMARY
Due to wayland's performance issues, i prefer to boot to X11 instead, however,
when compositor is "on" in an X11 session, mouse cursor flickers like a broken
florescent lamp. It also become invisible sometimes until you move the mouse.
It also momentarily glitches visually into some other shape, when you move the
mouse over various items. When i turn off the compositor in KDE, the problem
goes away. But of course, disabling the compositor brings screen tear.
STEPS TO REPRODUCE
1. Boot into an X11 session with the compositor on.
OBSERVED RESULT
Mouse cursor flickers, glitches (visually) and even becomes invisible.
EXPECTED RESULT
Mouse cursor should always be visible and solid even with the compositor on.
