Description

There are crashes on QCocoaScreen::deliverUpdateRequests().
I started noticing this in our users' crash reports on AppCenter right after we switched on Metal RHI
backend. There were no such crashes with OpenGL RHI.

Unfortunately, I have no any reproducer at the moment.
I can only guess that this might happen during destruction of child windows.
