Artifact blinking on the screen

[Mister Fab]

Hi all,

I have a problem with a fresh new install of Ubuntu Mate 20.04
Since the machine start, the screen is blinking with artifacts

I don't have this problem with RPi OS with the same SDcard, the display works perfectly.

Also in the screen configuration menu, I can see "Unknown monitor" and I can't change the parameters.

Has someone got an idea on how to fix this?

Use this Ubuntu image as it works for everything unlike Ubuntu's
I tried to get things working with the pure Ubuntu but things kept failing to work as expected
Loboris has fixed all the problems in the Ubuntu image. Get it here:

Thank you for your answer.

I use a raspberry pi 3 B+, does this image work on it?
