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.
