QMenu turns invisible when switch monitors on Win10
-
QT version: 5.12.0
The software becomes abnormal when the number of monitors changes.
For example, initially there are two monitors and the software runs well. However, when one monitor is unplugged, all the menus (including right-click context menu and dropdown menu) in the software would never pop up even when the unplugged monitor is reconnected.
Oddly, although the menus are invisible, when click on the original position of the menu item will trigger the corresponding action.
There is no such issue on Windows 7. The problem occurs only on Windows 10.
Is there any solution to the problem? Thank you!

Hi,
Qt 5.12.0 being old and obsolete, the first thing to do would be to test with a more recent version either the latest 5.15 or Qt 6.
