I think this might be similar to what I've experienced lately. It seems like it is definitely triggered after a window resize, both manual and automatic. After the resize, button clicks seems to fall through the window to whatever is behind it. Reproduction is reliable so I can even record a video of it happening if it helps.
This is on Ubuntu 23.10, mutter=45.2-0ubuntu3, Xorg.
