--- Comment #8 from Neil Roberts <neil at linux.intel.com> ---
I was thinking maybe the best thing to do would be to just remove the check for
a zero-sized framebuffer entirely. This check also bails out if the scissor
does not intersect with the framebuffer. However this can cause problems even
without Kristian's patch in a contrived example. If the scissor is set to just
outside the bounds of the framebuffer and then the framebuffer is resized to
intersect with it before calling glClear, then _mesa_Clear won't yet have the
new size so it will incorrectly skip out the clear entirely. I'm not sure
whether it's a good idea though because there is nothing further down in the
driver to bail out and it does end up putting a clear command in the batch
buffer.
