Description:
My office set-up (Windows 11 laptop plus large external monitor) launches Libre Office -- home screen, Calc, Draw or Write -- on demand to the full screen on an external monitor.  When I shrink the Libre Office window to less than full screen on the external monitor ALL drop down menus are blank.  When I drag any reduced screen back to my laptop screen the drop downs all re-populate.  When I drag the same reduced screen back to the external monitor, the drop downs remain populated?

Steps to Reproduce:
1.Set Libre Office to open full screen on external monitor (mine scales up to ~ 150%
2. Close & re-open Libre Office, either by double-clicking a document or launching Libre Office. (didn't try launching one of the apps w/o a document) and shrink the screen to something less than full screen
3. Close & re-open Libre Office or a document.  Click any drop down; they're empty.

Actual Results:
Blank menus until I drag the same window back to the laptop screen.  Then the menus re-populate.

NOTE! Resetting profile seems to have resolved the issue BUT when I first moved the LibreOffice screen from the laptop to the external monitor the Libre Office window only -- not the rest of images -- went spastic, jittering all over its window.  When I expanded & reduced the Libre Office window the jittering stopped.

Started all over with brand new user settings (very few changes from "factory settings"

Expected Results:
Drop down menus should always be populated.
