Maybe filed on wrong package sorry (maybe why I'm not finding it). Issue looks identical to https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- nouveau/+bug/1942561 (that was impish) Post-install checks I adjusted monitor to match my setup (one display above the other) On lower display, the background is now blocky-somewhat-flashy (on changes to screen (including just moving the mouse IF mouse is on the other screen! but not my-lower screen) or blinking of a cursor in a data entry field) The issue is only background, if TERMINAL or any window is maximized; the issue is gone (ie. blocky-flashy(changing graphics) is only occurring on background; windows are drawn correctly on issue. See attached picture. As I continued to use the system though (exploring it as I type this up on my primary box) the issue suddenly disappeared.. and it's now good.
