--- Comment #5 from Neil Roberts <neil at linux.intel.com> ---
I can replicate this problem if I use the Cairo image backend. It goes away if
I apply this patch:

http://lists.freedesktop.org/archives/wayland-devel/2013-December/012650.html

That makes sense because without that patch there are two things attaching
buffers to the triangle surface. Perhaps when the demo is normally running the
buffer with the triangle normally ends up being attached last so it looks ok.
However when the surface is being resized maybe it will sometimes cause Weston
to repaint in-between attaching the secret cairo buffer and the triangle buffer
so it renders garbage.
