Bug Description

Apologies if this is filed against the wrong package. Please re-assign it if so.

After upgrading to Ubuntu 20.10, the Unity title bar (with the application title, time, wifi icon, etc) flickers constantly. The rest of the screen does not flicker.

This appears to happen after xscreensaver runs, but only some times. I don't see any pattern to which times.
