I've seen this error on Ubuntu 18.04 and now on 20.04 I've never reported it yet but I think the time has come. In a random time (~ once a couple of weeks) I see a blinking screen. Today I've recorded a video on my phone to show you how it looks. You can see it here: https://youtu.be/JiUu7Ydg6uM This is bug finishes when I do logout from my desktop. Could you help me eliminate this error?
