***


STEPS TO REPRODUCE
1. Open Krita and tap on any menu option with either a touchscreen or a stylus

OBSERVED RESULT
Krita will register my press as several pixels up from where I actually pressed it. This doens't happen when I click a menu item with my mouse, nor does this issue occur in any other application. Drawing on the canvas is also not effected by this bug. When I draw on the canvas, my movements are measured exactly where my stylus is.

EXPECTED RESULT
The menu item I touch on is selected.

We had a bug like this on Android, it was due to Qt's implementation of Android plugin. Something similar may be happening with your platform plugin, since it is XWayland. But I'm not fully sure.
