Qt 6.2: Menus Truncated initially on Windows

In my Qt 6.2.0 application menus are truncated on initial display after starting the program on Windows 10. On the Mac the problem did not occur yet.

This only happens once per Menu (once per Edit, once per Mode etc...) - but not for all Menus. It seems not to depend on the size of the Menu. Its always the last entry that will be truncated and in all cases the second last entry is a separator. If i choose the menu a second time it will be fully displayed:

If menus are rebuilt in response to a language change the problem occurs once again per menu.

This problem was only observed on windows using multiple monitors with different zoom factors / scaling.
