Comment 10 for bug 1882291

I've been seeing it too in 20.04 (Focal), using NVIDIA binary drives and Xorg. I usually see it on the top bar (has happened several times over the past couple of days) but I've also seen it at least once on the lock screen. It seems that moving the mouse pointer over the time corrects it temporarily until the glitch next happens.

I could run an apport-collect command on this bug if anybody is still interested.
