This is my main workstation; fully updated 20.04 system.
This glitch in 17.10 used to appear top monitor along left edge, it's moved as I noted prior comment to the top of some windows (but not all). In this badly shot video (sorry) it appears as flickering top of chromium (snap) & audacious windows on screen. There is no flickering evident on the gnome-terminal, or hexchat windows.
dell [optiplex] 960 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)
Note: This issue also occurs if I login with MATE as my chosen desktop (bloated system with many desktops), but NOT Lubuntu (LXQt) or Xubuntu (I probably should re-check, but I'm positive it doesn't occur there).
