[1] The glitch takes the form of the contents of new windows not being shown, only the frame. It only seems to happen with Gtk apps, primarily Thunderbird. I've tried futzing around with the Xorg acceleration settings, and I've been able to reduce but not eliminate the problem.
I've been seeing some weird X glitches similar to this a lot lately, both on a corporate laptop that runs Ubuntu 20.04.5 LTS with Intel video and also a Fedora 36 workstation running with NVidia drivers with a Geforce RTX 2080 Super. Same thing. Click on a Thunderbird message and I just see the outline of the message until I click on it or move the window a little.
Similar problem here for many years through many Fedora versions, plasma-desktop on Intel integrated graphics (both with nouveau enabled or disabled for the discrete card in this laptop).
After some days of activity it looks like things are randomly not pasted onto the screen, refreshes are missing, scrolling only refresh some zones etc. I usually use Shift-Alt-F12 twice to disable and enable compositing. This usually mixes things enough to work around the issue for a while, but the problem never goes away. It may be something related to buffer/pixmaps/something allocations, there was a suspicion that having a chat program with a constantly blinking icon would show up the problem faster.
No idea how I can investigate or report this.
