[nouveau] changing screen position, dash is gone, background is
black.. and flashing white on any attempt to operate anything

Incomplete
Status in mutter package in Ubuntu:
Incomplete
Bug description:
Ubuntu 20.04 LTS daily QA-test (live) on hp dc7700 (c2d-e6320, 5gb,
nvidia quadro nvs 290)
Background:
Another exploration of http://launchpad.net/bugs/1869571, primarily as
I want screen dump to file bug upstream as requested; this box shares
screens of hp 8200 that had it before, so I'd expect can easily re-
create it.. I hadn't re-create that issue on this box though.. This
box has menu on display I prefer, so maybe has cables reversed to hp
8200 used earlier in 1869571, mentioned in case related - but
different issue
What I did:
Opened `displays` to adjust to match setup (vertical alignment of screens);
and on hitting "apply" the system has gone strange
- black background (both displays)
- lots of (white) flashing on mouse movements if near panel/dash
- dash is gone, like it has background color but icons gone, now only ~half
height of monitor (it was screen height before apply with icons)
Menu items could no longer be operated as not viewable (let alone
white flashes being very annoying)
I pressed printscreen to get screencapture once `ubuntu-bug` was
started; and the dash was re-drawn!!? (it was not there after screen
position was changed & until printscreen was hit)...
Printscreen also stopped all white-flashes, and the system is now
operational again?
