Screenshot of the invisible UI

Since Thunderbird 115 came out if I leave it minimized then play a game or run any fullscreen application for a while, the UI becomes invisible or a glitchy mess.

See attached screenshot.

STEPS TO REPRODUCE
1. Launch Thunderbird
2. Minimize it
3. Launch a game, close it
4. Restore Thunderbird

Since this only started happening after upgrading to Thunderbird 115, it's logical to assume it's a bug in the app itself. Can you report it at https://bugzilla.mozilla.org?
Comment 3 Federico Dossena 2023-08-07 22:27:01 UTC 
I reported it here because it looks like a compositing issue that seems to be specific to KDE, version 115 introduced client side decorations so I thought it could be related. It's not something specific about my system either, I did a clean install of the OS and as soon as I added my accounts it started doing it again.

I don't see reports of this issue on their side so I should probably report it there too.

Indeed, it's possible we're doing something wrong, but we don't have bug reports about CSD apps in general exhibiting this issue. So shy don't you start there, and if they determine it's our problem, we can re-open this.
