[Mr A Heaps (aheaps)]

compiz works without unity or vice versa seems way around it is to use the settings in the lof in screen and have 2 accounts one running unity the other compiz seems to affect the graphics card nvidia most of what i've found out is that the bug happens on machines running nvidia will update soon as got several different cards will try others first

[Mr A Heaps (aheaps)]

lof in meant log in sorry guys /gals
