Why are you hiding to resize? I simply do a redraw of the image (if
necessary) and do a buffer swap.

Are these errors the result of the XUnmapWindow() or the result of
something previous? Try running in -sync mode and trapping the error
with the debugger as I suggested to another poster recently. A map or
unmap should cause those errors. I suspect what's happening is that
some X call earlier on is causing the error and it just gets detected
at the XUnmapWindow() call.

My code is virtually identical to yours in respect to creating the
GLCanvas. I did make a few mods to gl.c but they were mostly minor
stylistic changes, as I recall.
