Greyish patches and distortion-like for some words when browsing.

Hi!

I'm on a Dell xps 9310, ubuntu 20.04, Firefox version 84.0.

Whenever I'm scrolling or moving the mouse over the screen while on Firefox, I get greyish patches of pixel-like blocks over the screen. As far as I'm concern, it just happens on firefox as of right now and on no other browser (Chrome) or other apps.

I tried something that was suggested over another problem and go to preferences->General->Performances-> Untick the 2 boxes, but it doesn't solve the problem.

Anyone have any idea what might be happening here?

Thank you!

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting for changes to take effect.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

Well, looks like I need to read better. I had tried the solution suggested by cor-el but hadn't restart Firefox. After the restart everything is fine!

Thank you both for your time!
