Hi Jonathan
This has been reproducible since the fresh Wheezy install. It will be
hard to make a screen-dump of this because of the speed at which the
artifacts arrive and depart. It all happens within the time it takes
to click a menu item in say LibreOffice and the full menu appearing in
its full-length drop-down state. It is only visible at all because of
the inherently slow frame rate that exists here. glxgears indicate an
average of 55fps - an inaccurate test I know, but does at least show
the ball-park figure. My eyesight/brain has always been able to pick
up this sort of problem. The slow frame rate is really the essence of
this problem. Finding the solution though is something else entirely.
I'll get the rest of the requested stuff off to you ASAP - today probably.
Best regards
Jack
