As you might imagine, clipping bugs are really nasty to fix.

Thanks. I'd love to see this cleaned up and automated so that we can
verify that it works. I'd suggest having it run against a server that
isn't running a window manager or compositing manager so that it doesn't
fight those.

You could also have it run entirely within another window to avoid
interactions with the window manager, but that wouldn't test the root
case (which is often special).
