Well, it helps a bit. I haven't seen any lockups after enabling that option, but
there are still graphics glitches: OpenGL screensavers that operate on a
screenshot no longer work.
For instance, GFlux which shows a screenshot being shaken like a carpet now only
shows a solid grey colour moving about. MirrorBlob, which used to show something
like a magnifying glass moving across the screen doesn't show anything at all.
By the way, do you know if the agpgart bug is likely to be fixed?
