<pre>The crash occurs on the instruction to set a colour buffer (with Y-tiling) that
is currently being fenced with X. It is used earlier in the batch as a Y-tiled
texture. The hang could be at the pipeline stall at the end of that sampling -
hard to say for sure. At any rate, that we have a dirty fence register seems to
be the most likely explanation.</pre>
