--- Comment #1 from Ian Romanick <idr at freedesktop.org> ---
If a regression bisects to a commit by an Intel employee, please assign the bug
to that person. Otherwise they may not notice the bug.
Does this problem still occur? It should have been fixed by these commits:

glx: Pass NULL DRI drawables into the DRI driver for None GLX drawables
GLX_ARB_create_context allows making a GLX context current with None
drawable and readables, but this was never implemented correctly in GLX.
We would create a __DRIdrawable for the None GLX drawable and pass that
to the DRI driver and that would somehow work. Now it's somehow broken.
The way this should have worked is that we pass a NULL DRI drawable
to the DRI driver when the GLX user calls glXMakeContextCurrent()
with None for drawable and readables.

i965: Move intel_prepare_render() above first buffer access
The driver is supposed to ensure buffers before any drawing operation, but
in
do_blit_drawpixels() and do_blit_copypixels() we inspect the buffer format
before calling intel_prepare_render(). That was covered up by the
unconditional call to intel_prepare_render() in intelMakeCurrent(), but we
now only do this on the initial intelMakeCurrent call for a context
(to get the size for the initial viewport values).
