Description empyreal 2021-07-23 22:22:17 UTC 
SUMMARY
Tried two versions of gwenview: 19.12.3 and 21.04.0. Same problem. When I try dragging gray square handles, they do not change cropped area. Handles stay on image borders and do not move. I can crop images in Advanced Settings by changing numeric values only.

STEPS TO REPRODUCE
gwenview 19.12.3 and gwenview 21.04.0
I use Wacom Intuos Draw small and it won't do this crop function.

OBSERVED RESULT
gwenview 19.12.3 and gwenview 21.04.0
I connected simple optical mouse and this crop function works. With optical mouse I can crop both ways: by dragging handles and by changing numeric values. But with tablet — no way — can't crop by dragging handles.

EXPECTED RESULT
Expect Wacom Intuos Draw to work fully as optical mouse.

Similar problem with VirtualBox.
Solution: Exec=bash -c 'QT_XCB_TABLET_LEGACY_COORDINATES=1 VirtualBox %U'

Comment 2 empyreal 2021-07-24 11:15:56 UTC 
Only Exec= option was changed in virtualbox.desktop
Exec=QT_XCB_TABLET_LEGACY_COORDINATES=1 VirtualBox %U
in /usr/share/applications/virtualbox.desktop does the trick - I can use Wacom

Only Exec= option was changed in org.kde.gwenview.desktop
Exec=QT_XCB_TABLET_LEGACY_COORDINATES=1 gwenview %U
in /usr/share/applications/org.kde.gwenview.desktop has no effect - I can't change crop area with Wacom
Comment 3 empyreal 2021-07-25 14:24:28 UTC 
Same problem with newer Gwenview in Mageia 8 and Manjaro 21.07 releases (contains QT 5.15.2). Can’t change crop area with Wacom Intuos Draw Pen S North White (CTL-490DW-N).
Comment 4 empyreal 2021-07-31 09:52:43 UTC 
Also I can't drag picture with Wacom pen when it is scaled. I think the root of this issue is the same, so I add comment instead posting new bug report.

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)?
