SUMMARY
***

***

In Plasma 5.24's Wayland session (tested specifically on Fedora Linux 36, but also applies to Fedora Linux 35 when it's updated to Plasma 5.24), when the standard pointer cursor changes to another cursor, for example the I-beam (the one that shows over text fields) or the pointing hand (that shows over hyperlinks), the cursor goes off-centre; when the cursor changes back to the standard pointer, it goes back to normal. This does not occur on the X11 session and did not occur in Plasma 5.23's Wayland session either.

STEPS TO REPRODUCE
1. Login to the Wayland session and mouse over an editable text field or a hyperlink
2. The I-beam / hand cursor goes off-centre
3. Login to the X11 session and do the same; it works as expected

OBSERVED RESULT
I-beam / hand cursors go off centre

EXPECTED RESULT
The cursors stay centred, as what happens in the X11 session and in previous versions of Plasma's Wayland session

In what apps are you seeing this, specifically? Also what scale factor (if any) are you using?

It seems that a recent update changed this - now the cursor doesn't just stay off-centre, it now jumps off-centre for a fraction of a second. This happens across the entire desktop in all apps. I made a short video here so you can see it. https://www.youtube.com/watch?v=bfv1wMdCgb4
