Hi guys
I send a reply to the list a couple of days ago, but I attached my exe file
and it seems it was blocked but hotmail...
First, thanks a lot for all your replies... Jesse, I've made the changes
proposed in those patches, but it didn't work :-(
After further inspection, it seems the problem is when I call wglMakeCurrent
for a context which shares display lists with another context. I've attached
the program and the source code, so you can try it.
This is the output of the trace+opengl:

Major opcode of failed request: 144 (GLX)
Minor opcode of failed request: 5 (X_GLXMakeCurrent)
Serial number of failed request: 120

My guess is that when we call wglMakeCurrent for the context with the shared
lists, it has a VISUAL_ID of 0x23, but X11DRV_setup_opengl_visual chosed a
Visual ID of 0x21, and hence the BadMatch error.
As I said, this program works just fine in Windows, so we must be doing
something differente in wine
Any ideas/hints?
Thanks
