Description poperigby 2021-11-14 19:33:26 UTC

SUMMARY
If the cursor is set to size 24, it will be as big as size 36, and if set to size 36, it will be as big as size 48. But, this is only the case when hovering over anything built with Qt. Plasmoids, KDE applications, etc. The cursor is normal size if hovering over Firefox, Thunderbird, GTK apps, and window titlebars.

STEPS TO REPRODUCE
1. Login to a Wayland session
2. Hover over something built with Qt

OBSERVED RESULT
The cursor is one size bigger than normal

EXPECTED RESULT
The cursor is the same size it would be on X11

What you're reporting is actually not a bug, but the intended state of affairs.:) If you use a 24px cursor and 150% scaling, 36 is 150% bigger than 24, so that's expected. You just got used to this not happening on X11, which was always a bug.

However there is a bug here: thr fact that this *doesn't* happen for all apps. You said it happens with Qt apps, but it's not working for which other apps? GTK? Electron? Custom UI toolkit like Blender? Every other apps besides anything built with Qt?
