C22-820 All In One ,Video flickering and Dark ones tend to dark purple or have greenish zone

Hi, the video of my Acer C22-820 All In One has got some problems. Images are not distorted, I can browse and see websites and videos perfectly, but the colors of the desktop as well as some borders in Gmail and some areas here and then have "wrong" colors. Dark ones tend to dark purple or have greenish zones, light ones are sort of pink or light blue with subtle lines.

This happens in any browser, and it is displayed randomly. Sometimes this effect only lasts some second, some other some minutes, and it disappears without any intervention.

Drivers and Windows 10 are uodated. No recent apps added.

Any idea?

Thanks in advance!

Does this issue appear in screenshots, video capture, or on an external display?

Yes, this issue appears in screenshots too. No external displays connected, so I can't check this.

If the artifacts show in a screenshot the same as they appear on the monitor, it's not an issue with the display itself. More likely an issue with the GPU or it's drivers.
