If you want to give a stab at fixing this, the patch from comment 14 is probably still the latest attempt I know of. At the very least it needs to be retested with current versions of various GL drivers.
Unfortunately that patch doesn't apply cleanly to current versions of wine. I've tried to reset to wine-1.5.0, where it does apply and seems to fix the problem. I guess someone will have to rebase it. I'm not sure though whether it's worth trying to do (for me at least), as there are some doubts about its quality/correctness expressed in the author's message.
