Fixed by the following commit in master: commit c9c39812b91c8104bc0bea16053312547846249c Author: Jason Ekstrand <jason.ekstrand@intel.com> Date: Wed Apr 5 13:41:56 2017 -0700 i965/blorp: Bump the batch space estimate Commit f938354362655a378d474c5f79c52cea9852ab91 recently increased the alignment on vertex buffer data from 32 to 64. This caused us to consume a bit more batch than we were before and we now go over the estimate by a small amount on certain blits on gen8+. This commit bumps then gen8 batch estimate by a bit to compensate. Haswell and older still seems to be well within the limit.
