Comment 1 for bug 795464

My aplologies for the double post but I forgot to mention two things in my original post:
1) I've tried activating the "Copy to texture" plugin but it made no difference
2) I'm running compiz with emerald on ubuntu classic because at first start a window poped up saying that I don't have a good enough videocard to run unity, which is strange because I have a Raden HD 4500 with firegl and that should be enough - it is enough to rotate a transparent cube deformed to a sphere. But I was gonna switch to classic anyway.
