Well, then I assume DMA texture upload does fix this entirely. Good news.

Sounds reasonable. xcompmgr works with large texture chunks, they should never
ever trigger my workaround.

Michel, if we get DMA for the non-DRI case as well, I won't bother rewriting my
patch to this case. No need to hurry, though, I just want to schedule my work.
