Sorry about the post, my direct mail to you bounced.

The solution to this at the Xlib level is after each XCopyPlane,
wait until you get a GraphicsExpose or a NoExpose event.
Better yet, don't do consecutive XCopyPlane calls unless
you have had a GraphicsExpose event to repair damage or
a NoExpose event to let you know there is no damage.

This assumes the GC graphics-exposure flag is true.

I am not sure what your toolkit is trying to do,
but if you have source, you should be able to fix it.  Somehow.
