Comment # 3 on bug 93648 from Ilia Mirkin

I tested on a SNB and couldn't reproduce any artifacts on the apitrace (after
forcing ARB_conservative_depth on). Even if I could, it'd be very surprising if
the issues were related. Unless you have concrete evidence to the contrary, I'd
keep it to one bug per issue that you see. Issues can be combined later on, but
are difficult to break apart. Switching this one back to radeonsi.

Any issues you see on other hardware should include an apitrace taken on that
hw.
