or “export QT_XCB_TABLET_LEGACY_COORDINATES=1”
but, doesn't this method cannot fix this issue for ubuntu user. why? i don't know.

It also doesn't work for grabbing the handles when you crop an image

Same here. I use a XP-Pen Artist 15.6 Pro with Digimend drivers on Gwenview 23.04.3 and the problem is there.

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Gwenview 25.08.0 (the latest released version)?
