sorry, i was talking rubbish.
the bug is nothing to do with unbuffered windows, and is documented in
the rio code:
/*
* BUG: should interlock so applications don't change screen
* while tmp[] holds backing store
*/
it's not a problem deep in the drawing code at all - it's just that
rio (well drawgetrect()) is trying to be efficient and drawing the red
borders directly on the screen.
to be honest, it should be quite fast enough if it just allocates new
windows every time it moves the border - that's what i did in the
inferno wm and it works fine, as smooth as you like.
