Bug and Monitor Arrangement

SUMMARY
Menus from right-click or the menu bar are misplaced in a dual monitor setup with a particular panel arrangement.

STEPS TO REPRODUCE
1. In a dual monitor setup, arrange the secondary (smaller) display aligned in a horizontal line at the bottom.
2. Add an empty plasma panel on top of the secondary display.
3. Open, for example, the VMWare or OrcaSlicer app on the primary display and place it at the top of the display.
4. Click on the 'File' menu, or right-click context menu.

OBSERVED RESULT
The menu appears offset by the panel position on the secondary screen. 

EXPECTED RESULT
The menu should appear right under the mouse/menubar.

Comment 1 Aleksey Zagorodnikov 2025-10-25 17:33:01 UTC
To clarify, without a panel on top of the screen, this bug does not happen.
It also occurs only for a small group of apps, not quite sure what they have in common.

VMWare Workstation 
OrcaSlicer
