I believe you should be using XCopyArea to copy the pixmap to the
window.

In any case, if you can get away without the pixmap, do so. I find
that pixmaps use more of the server resources than I would like.
When running an X server on my PC (DEC's PCSA PC DECwindows),
programs with pixmaps eat up available RAM and eventually cause
disk swapping.
