--- Comment #2 from Ilia Mirkin <imirkin at alum.mit.edu> ---
The thing immediately coming to mind was the workaround I added for dealing
with mismatching color/depth render targets. The "fix" was to just not render
to depth at all, but that may mess up other things of course. (Not the least of
which is that the depth texture will remain untouched.)

To start, you should get an apitrace (https://github.com/apitrace/apitrace) of
the failing application. This should help determine what's going on. Make a
debug mesa build and see if the driver outputs any "aaaah, i don't know how to
handle this" type messages.
