I have spotted this patch by Jim Duchek that claims to solve double buffering flicker with Xinerama.

This is great news!! Unfortunately I cannot apply it because the code of the 1.9 release I have appears to be in C while Duchek's is in C++.

I do not know why this happens, so I would like to know how we can get a patched version of the code, or some pointers as to how to patch it.

Many thanks, and regards.

Keep up the good work
