Oh wow, now that I've actually looked at the issue in more detail, I'm pretty
amazed that you actually managed to hit this issue! Congratulations! :)

The true analysis is a bit different, I would say. The flush ends up accessing
the texture because it does an automatic re-add of all resources when starting
a new CS. This should not affect the ability of the other thread to do a
texture invalidation (you'd just kill performance by introducing an unnecessary
stall).

The real solution is certainly different. I'm currently looking at other
texture-related races as well, this is just one additional one to take care of.
Thank you for the report!
