So a tiny coloured square in the top right of your screen. It that correct?

It is not a colored square, it is a TB window reduced to this size, or it freezes and there is only a black window. And this is on each of my 10 computers since SUPERNOVA.

Another screen and so several times a day... I blurred sensitive data.

What is your anti-virus software?

Windows Defender

Try to start Windows 10 in safe mode with networking enabled.

Does the problem go away?

Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.

Unfortunately, no changes. The issue still exists.

I'm still testing, I'm on step 10 and currently no changes

I took all the steps, the problem is still occurring, the update to version 115.8.0 did not help

Your screen shot is super small, but looks messed up. So my guess is it's a graphics issue.

every screen is fhd it's not a card problem because 9/10 computers in the company have the same problem

I received information yesterday from another company that also has the same problems but does not report it but is hoping for another update that will fix it
