Hi,
I don't think we want to go this way. First of all we want to emulate win32
opengl. If windows does this we MIGHT have to do something like this. Second
all opengl calls hit ENTER_GL / LEAVE_GL and these few extra calls affect
performance.
Personally I think that when you are hitting such an X11 lock exception that
there is just a bug somewhere in wine. E.g. in case of a Direct3D app a piece
of wined3d not doing proper locking. The same can be the case for plain opengl
apps where a call might not have called wine_tsx11_unlock.
Regards,
Roderick Colenbrander
