--- Comment #6 from James Legg <jlegg at feralinteractive.com> ---
Unfortunately, I've been unable to reproduce the bug while replaying a trace
captured with apitrace (the bug occurs while capturing however). Capturing
traces from builds of recent Feral titles available on Steam will be difficult
as we've tried to avoid Steam injecting its overlay in the options window when
glXSwapBuffer is called, and this also prevents apitrace from capturing those
calls (which are important for this bug).

Forcing Mesa to call st_validate_state in prepare_draw in
state_tracker/st_draw.c, regardless of st->dirty, works around the bug. I'm
still investigating, and trying to make a minimal reproducer.
