Nah, I wanna hear about bugs that have affected you that you can confirm are bugs :-)
I’m glad you asked. 5 seconds ago gnome froze and sent me back into the login screen and closed all the apps I had open. Ask me again in 20 seconds and I’m sure I’ll have a different bug for ya.
Most of the issue is that they’re unreliable. Sometimes the app will work. Sometimes it doesn’t. Sometimes you have to fiddle blindly with flatseal settings, which ones? Who knows? Guessing is part of the fun.
It’d be a great thing if it just worked.
