Did following tests:
1. On Windows 10: works as expected. No display freeze.
2. On Gnome, X11: display freeze
3. On Gnome, Wayland: application freeze
4. On Kubuntu, X11 with VS Code (Electron App): display freeze

All this leads to the assumption, that it is a problem of the various display managers or 
the way Qt interacts with them.

Same happens when you set a breakpoint in a method showing a menu. KDE grabs input focus 
and does not release it, but the program is stopped due to the breakpoint. We hit a 
deadlock situation. Unfortunately I haven't found a way to prevent this. Any help is highly

If breakpoint is hit during pop-up display all KDE environment freezes and the only way out is to switch to console somehow and kill debugger process.
In the file attached try to put breakpoint on the line with print statement, run under debugger and try to expand combobox and select some item.
