Bug#682099: xserver-xorg-video-ati: EXAPixmaps=On screen tearing at high resolution under certain configurations

[James Robertson]

Update...  Setting option

Option "NoAccel" "true"

Has fixed the problem.  I haven't noticed any problems having this
enabled in the way I use my computer, videos, glxgears etc. all work
ok.

So I suppose this bug report can be closed if desired.

The only other option I was going to try was using a Display port to
DVI adapter from the side of my laptop to replace the VGA from the
docking station.  If I purchase one to  try that I'll let you know.

Regards,

James
