Description Kath 2024-01-12 19:30:14 UTC 
SUMMARY
If the "Capture rectangular region" keyboard shortcut is used, while using a drawing tablet configured with "Target Display: Follow the active screen", it may sometimes move the tablet's cursor to another screen. This makes it impossible to use the tablet pen to select the area to screenshot on the active screen, although alt+tabbing seems to allow moving the focus between screens once the issue occurs.

The screen the cursor is moved to seems to be consistent, and is not the "Primary" screen in my case. 

STEPS TO REPRODUCE
1. Connect a Drawing tablet, configured with "Target Display: Follow the active screen"
2. Focus a window on a particular screen with the tablet pen to make it the active screen
3. Press keyboard shortcut to "Capture rectangular region"

If the issue cannot be reproduced, try again with the cursor initially focused on a different screen.

OBSERVED RESULT
The cursor controlled by the tablet pen is moved to a different screen

EXPECTED RESULT
The cursor remains on the active screen to allow selecting a rectangular region on the previously focused screen
