[Chris Guiver]

** Description changed:

- I'll add more detail shortly..
+ Kubuntu 18.04.5 QA-test on daily on
+ hp dx6120mt (mini-tower, pentium 4, 3gb, winfast clone of nvidia 7600gt)
  
- This issue is video related I believe, and won't impact 18.04.5 release
- - so I'm just recording for purposes so I can move to next test.. as I
- type this, the diagonal images are static, however as the cursor moves
- to the next 'line' in the browser page, the effects change briefly..

- it's flashing on major changes of display images, and would be difficult
+ it's flashing on major changes of display image, and would be difficult
  to use, possibly risky if user is prone to seizures...

+ -- QA-test comments were  (slightly edited)
+ 
+ reboot, greeter has a weird wrong-looking-logo/image above username but
+ I'll ignore it
+ 
+ logged in and weird graphics on background... nvidia issues I bet..
+ 
+ install looks good ...but issues with video, weird strobe/flashing
+ effect as detail on screen is re-drawn.. I'll file bug for records
+ 
+ I've take some photos .. will upload to bug report later..
+ 
+ I logged out & this time I have a KDE logo in the image / above my
+ username! I had no idea that was the image last time (it was so
+ corrupted, and blue wasn't a color in it pre-login)
