You need to manually apply the latest OpenGL patch for winex11.drv which is 
posted on wine-patches. I am hoping that this patch will be applied to the main tree.

Some disagree with how cleanly it solves the root cause but it does fix this 
regression so I think it probably would be better committed to the tree than not.
