Please attach /var/log/Xorg.0.log and the output of dmesg.
Can you upload the video somewhere?
If not, please provide more details about the glitches, e.g.: Are they always visible, or only intermittently? If the latter, how often? Does the vertical location of the glitches change or is it always the same? ...
I set the 120Hz and restarted. Then I opened Konsole and got the results and put then as attachments.
Finally got a video and put it in Youtube:

I cant get the video with tools like Kazam or SimpleScreenRecorder. I have to grab it with a external camera.
The glitches are intermittently. The image cam be fine for a fell seconds then the glitches show themselves.
