I should add: We've also tried to reproduce it by changing screen
scaling options while the app is running, as well as changing the
monitor setup (plug in/out external, move application back and forth)
while the app is running. But so far no luck. We have found some HiDPI
issues of course, and some other minor annoyances, but never this
particular issue, which is more serious since the menu bar is
completely outside the window frame.
