[Interest] mac app crashes if you plug in another monitor

Which version of the Qt Libraries are you using?

What macOS version are you using?

Can you give us more details about your hardware setup? Is this a laptop where another monitor was hot plugged? Was this a desktop that got a monitor hot plugged? What are the specific mac models you are using (helps to see if it might be a GPU issue).


Is the crash exactly reproducible?


FWIW: We are on Qt 5.10 and 5.12 and the few times that I have unplugged and plugged in monitors I have not seen our Qt Widget based app crash.
