Insufficient information to say with any certainty, but I have a guess.

You say nothing about where you get _gc from.  I suspect it may be the
default GC of the screen, or perhaps a GC created early on for general
use.  In any case, I suspect its depth is that of the screen, and
you're on a display whose default screen is not one bit deep.  Thus,
the GC is incompatible with the drawable, and you get a BadMatch.

If this isn't it, I would need more information.
