Re: Windows from any application turn black when too large
If you turn off desktop effects, do you still have the problem?
This looks like something that used to happen to me a few years ago using compiz, and it turned out that the desktop effects caused the video memory on the card to be used up.
I never see the problem now, but I have a lot better card with more video memory now also.
What card do you have, and can you tell how much video memory is on it?
