Firefox disaplayerror after Update on last version 89

[Tobias Schimpf]

After the last Update from Firefox Browser to Version 89 Firefox is unsuable. The Program starts but the window is somehow transparent and white. I removed and reinstalled Firefox but the problem is the same. My computer is an Amd Mashine running Ubuntu Mate 20.10 Mate 1.24.1
I took a Screenshot.

Thanks for the report Tobias. Is this reproducible everytime you launch firefox?

Could you please run the following command to attach further information to the bug report?

Hello Olivier,

thanks for your reply and yes I can reproduce the bug. Bevore I reinstalled it I removed all Preferences.

Now I ran the Command above and got a Mail with this report

I hope this helps to find the Issue

I also have this issue on Hirsute and 89.0+build2-0ubuntu0.21.04.1

Strangely, in the Gnome overview, all of the firefox windows have correctly rendered previews, however when you take a screenshot of an open firefox window, it comes out either blank, or with a transparent checkerboard pattern. The actual image seen on the monitor is a white screen.

My workaround for the moment is to downgrade to an older version
sudo apt install firefox=87.0+build3-0ubuntu4

Then launch Firefox once using the command:
firefox -allow-downgrade

And for now I have held the package in apt to prevent upgrades to the broken version:
sudo apt-mark hold firefox

I saw this comment for a similar issue:

Setting layers.acceleration.disabled = true before upgrading to FF89 makes the issue go away, but now I don't have acceleration for this "feature".

Since it seems to be acceleration related, here is some info on my graphics:
