I may have misread your post. It now seems to me you've built an X server with
your patch for your own use; you were just needing some acknowledgement from the
Cygwin folks of the issue you reported.
In any case, anybody else who runs into the flickering window issue and needs a
workaround, you can pick up a patched X Window server (64-bit) that I've placed in
a public location: http://maxrnd.com/~mark/cygwin/x86_64/XWin.exe .
