Lenovo Ideapad 130-15AST 20.04 distorted and unusable

I'm not all that experienced at filing bug reports here so I have included the attachment of the photo found at the forum link.

The picture in the community forum link is what the MATE 20.04 live USB boots to.
I first upgraded from 18.04 using do-release-upgrade. The result looked like the photo as well.
Then I reinstalled 18.04, upgraded to 19.10, which looked and performed normally. I then upgraded the 19.10 install to 20.04 with the same result as the photo.
I also tried with a different flash drive just to rule that out.

Then I made the live USB of the 20.04 image and booted it to what you see in the forum post.
I made a live USB of both Stock Ubuntu and Kubuntu 20.04 and both worked just fine.

Until I tried the other two flavors I was thinking it was system specific, but after they worked normally it seems to be a MATE specific issue with this system.

It appears to be only a display problem. The DE is completely unusable with the mouse, but I can launch a terminal and run commands, although the terminal is just as distorted as the photo above, so you can't see what you are typing or the resulting output.

I learned today that this is affecting Xubuntu as well as MATE and is apparently a known bug with the AMD driver that has been reported upstream.

A temporary work around for MATE, which I have not tried, has been posted in the community forums:

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1875944

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

I added the apport information with the system running 18.04. It isn't possible to submit the info when on 20.04 as the display is unusable.

You may find the following information useful. It looks like Ubuntu needs to add these fixes ...
