I once had a problem with artifacts (blinks) during screen recording and during screen sharing (in video calls). Then after one of updates the problem has left, but now has appeared again.
Screenshots from video:
On duty, I have to make video calls and share the screen. Also, I often record the screen. My colleagues complain about artifacts and blinking on the recording during the screen demonstration. I have tried using many screen recording and video calling programs, but the problem is present in all.
I tried switching to use OpenGL 2 and 3. Changed settings "Tearing prevention", but it did not help. Artifacts disappear only when using XRender, but it does not suit me, as there is a tiring and blur effects disappear.
