Can you be a little more specific? Were you running Microwindows in
framebuffer mode or in X11 mode? How big was your image? What type of image
was it?
What was the context? Were you just trying to draw one image every once in a
while (like an icon) or were you drawing many times very fast (like in a
game)?
Have you tried using a offscreen pixmap? You could draw the image on the
offscreen buffer, and then copy it over as needed (copying is always cheaper
than drawing images).
