Comment 140 for bug 1568604

I agree with peerus (comment #139). I suspect that this bug is related to another program package, but I do not know enough to be able to suggest which package.

I have problems with graphics with a non-intel graphics chip. It turns pale (almost completely greyed out), and after switching to another virtual screen and back again, the graphic rendering is good again. See this link

There is another maybe related issue described at the following link
