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
