GraphicsExpose events occur when the source area for an XCopyArea() or
XCopyPlane() is outside the source window or obscured by another
window.
What are you doing in your canvas objects? Are you creating your own
GC? If so, you may want to set the graphics_expose member of
the XGCValues structure to False when you call XCreateGC().
Refer to your favorite Xlib manual for details.
