Hello,
I have a big problem. This morning I turned on my PC, I got to the desktop and a lot of black squares appeared everywhere, then disappeared, and then showed up again in different places, and so on.
Can you help me?

Hello everyone,

I also had this issue. I am on Firefox and in the latest version, in the top right corner of my internet page (the question mark), I clicked on "Troubleshooting Information" then "Repair Firefox".

The problem is resolved. I can't say the reason for those pesky black squares, but it's a solution to try; for me, it works.

If this can help other people experiencing this problem, I’m glad to have been able to help.

P.S.: I think it's simply a Firefox crash because in the crash report history (I keep all of them since I got this laptop), the latest one happened just before I noticed these black squares.
