Bug Description

I can consistently crash gnome-calendar by dragging it from one monitor over to the other monitor at the top of the screen so that it moves into full screen. It seems to move to that screen with the window resized but the contents not redrawn.

Focal with all updates as of 25-mar. Reproducible multiple times.
