Public bug reported:
I am experiencing intermittent graphical glitches. I couldn't find where
this had been reported before so please excuse the duplicate if this is
a known issue. I tried recording my screen to demonstrate what is
happening but, although I am seeing the issue on the desktop, it does
not show up in the video. I am using prime-select in intel mode.
