            Bug ID: 447797
           Summary: Mouse cursor glitching upon switching states in the
                    Wayland session
           Product: kwin
           Version: 5.23.4
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: wayland-generic
          Assignee: kwin-bugs-n...@kde.org
          Reporter: unixst...@protonmail.com
  Target Milestone: ---

SUMMARY

Whenever I log onto a Wayland session, hovering over links results in the mouse
cursor switching to the appropriate state, but while it does so, it briefly
moves to the side of where the cursor should actually be, before returning to
the correct position. This happens on both XWayland and Wayland applications,
Qt and GTK. I have tried to change compositor settings, but they don't seem to
help. I'm not using fractional scaling. This isn't my video, but it looks
exactly like this: https://www.youtube.com/watch?v=wCyTrt3TrAw

STEPS TO REPRODUCE
1. Switch to a Wayland session.
2. Use your mouse to hover over a link or anything else that changes the state
of the cursor.
3. Upon hovering over it, or moving the cursor away, it changes to the
appropriate state, but it does not transition smoothly. It moves to the size
for a brief second and returns to the correct position.

OBSERVED RESULT
Upon switching states, it jumps to the side for a small amount of time, then
switches to the correct state in the correct position.

EXPECTED RESULT
It should switch states without moving to the side or glitching.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:  openSUSE Tumbleweed 20211228 snapshot.
(available in About System)
KDE Plasma Version: 5.23.4
KDE Frameworks Version: 5.89.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
The same issue also happens on other distributions, themes (including the
default Breeze theme, cursor and otherwise), but only on Wayland, not on xorg.
None of the compositor settings solve or help reduce the issue.
