Just got around to upgrading a couple of computers from 18.04 to 20.04 and was disappointed to see that this bug persists. It happened on both a system connected to a 1920×1080 TV and one connected to an old 5:4 LCD monitor. Does anyone else experience this? Is there a bug report? (I can’t find one)

This is just the plain dialog too. Nothing is expanded, it just consists of a vast area of white space that pushes the buttons off screen. Sure you can use Alt or Move, but why should you have to?
