Good point.

I guess (if we go with your patch) we'll have to disable the
glCompressedTexSubImage2DARB() path when we're dealing with sRGB textures. But
(in addition to making wined3d even more convoluted than it already is) we'll
then need a way to distinguish sRGB textures from others. I don't know if this
is worth pursuing. You're the D3D/GL experts.

Or, the crash in Stefan's test app might have some other cause. There's lots of
strange bugs in the Mac OS GL implementation, as you are both well aware (and
you know about these primarily because CodeWeavers pays you in part to work
around them for CrossOver Games :). I suspect the reason is that, like much of
Mac OS X, it was (re)written from scratch. (Under the hood, it seems like a
completely different beast from the various Linux OpenGLs, from what I can
tell.) New code tends to have more bugs than older code. That, and the fact
that most of the upper OS layers, including the OpenGL framework, aren't open
source (so nobody outside of Apple gets to take a good look at them).
