@Be-ing Maybe util/widgethelper.h/.cpp? We already have a util/desktophelper.h/.cpp.

@Be-ing How to proceed here? This is a major issue in full-screen mode and should be a beta blocker.

[Be-ing]

I'm unclear what the best way forward is here. We could make a utility function for this, or we could figure out how to get Qt to do this automatically for CueMenuPopup.

I don't agree that this is should block the beta release.

I suppose we can adopt something from
https://github.com/qt/qtbase/blob/dev/src/widgets/widgets/qmenu.cpp#L2337

Failure of the pre-commit job is unrelated. No need to wait fro the remaining CI builds after the latest changes. LGTM.

Then hotcue menus aren't cut outside the window anymore. Thanks for the fix @Be-ing
