I noticed with Ubuntu 22.10 at random window controls disappear for Chromium, Firefox, and Thunderbird (all snaps) when using CSD. This happens when I swap between light and dark theme or when I wake up my computer for sleep.
could you report this to https://github.com/ubuntu/yaru ?

Did you check if a correspondent .deb from a PPA exhibits the bad behaviour as well?
A bit difficult to do that with Firefox and Chromium as they are snap only. I could installed Thunderbird as deb and test it out, and get the tarball for Firefox and see if that happens. I will need to test it out. But all other apps (that are deb) in my testing works fine.
