Some screen changes may cause segfault, e.g. putting Mac to sleep (related to: gdk_windowing_update_window_sizes)

I'd put my computer to sleep with a Gimp document open on the desktop, when I came back to it there was a dialogue box stating that Gimp had crashed with a fatal error: fatal error: Segmentation fault: 11. Gimp had not been funtioning properly for a couple of days, this coincided with me updating my Mac to Big Sur. Some of the tools weren't working as expected.
