Hi, I have the exact same problem after upgrading to Ubuntu 20.04 from Ubuntu 18.04. I have found that the issue goes away when I disable zoom in Settings -> Universal Access. This was never an issue in Ubuntu 18.04 for me with zoom enabled. At least now I know I can work around this issue by just turning off zoom but it'd be great if there was a real fix for this issue.
Have you gotten any response on the fix for this bug or have you found out yourself how to fix?
