I think that could be significant. I don't have that kind of hardware, so not a
lot of experience with VirtualGL, but if I understand correctly it redirects
some X11 / GL calls to a different GPU.

The main difference between before and after that commit is that we now
initialize GL and create the corresponding window earlier for ddraw. That means
that in some cases we may now have two GL contexts active at the same time
while previously we didn't. That shouldn't be a problem by itself, but I
suppose if something messed up X or GL synchronization you could get that kind
of BadDrawable errors. I suppose it would be useful if anyone could reproduce
this without VirtualGL, since we could rule that out as a factor then.
