I don’t have any advice, but I’m seeing bugs even in Windows. The right click menu in the system tray isn’t sized properly so half of it is cut off and there’s no way to select the cut off menu options, even with keyboard input.
I have to open up the entire app just to exit steam. I’ve seen other UI bugs too.
I think the new UI is nice overall but it’s very buggy. Might not even be an issue with Linux, just a buggy app.
