9 times out of 10 when I get that error, I find that I forgot to create
a new colormap with the new visual. You might also want to check that
you aren't trying to CopyFromParent anything else related to depth
(border pixmap, etc).

Yeah, I know, forcing the app to create a "colormap" for a TrueColor
visual is silly, but the protocol requires a Match error if you don't.
