"Lubuntu 20.04 qa-test install; flashing at sddm greeter when mouse at top
panel (pre-login)"
which reads very similar, maybe even same cause (similar pattern at
least in flashing), but occurs different positions on the screen.
This was not the duplicate I'm hunting for...

Title:
lubuntu groovy; flashing of sddm greeter
Status in linux package in Ubuntu:
Confirmed
Bug description:
Lubuntu groovy QA-test install.
On reboot, the login greeter (sddm) screen isn't nice, with areas of
the screen flashing white/black/white/black (maybe white & black each
second like a ":" might flash on the clock, only the ":" on the clock
is static)
likely package at fault should be xserver-xorg-video-nouveau

The
- drop down for session (not selected Lubuntu)
- language drop down (not US flag)
- white/black on login picture (not grey name)
flashes black & white on a cycle...
The top panel items will eventually stop flashing (ie. session &
layout) but time or certain actions cause the flashing white then
black in cycle to occur again.
** Expected Result
No flashing, its irritating & potentially a problem for some with
certain health conditions.
** Not new issue, it's occurred in the past
hp dx6120mt (pentium 4, 3gb, winfast clone of nvidia 7600gt)
I've had this issue before on eoan on hp dx6120 i believe but cannot
find bug report. The bug was likely not filed as that box was i386 &
support was being dropped when I noticed it so I didn't see any point.
It's not new, and no doubt relates to Nvidia cards, and I'm convinced
I've filed this before on dx6120 so if not eoan, disco, but I've not
yet found it.
