<pre>This is easily reproducible via unigine's heaven benchmark, simply running it
with normal tessellation settings results in the screen flashing black a few
times and then an eventual system hang before anything even starts to render. A
power cycle is the only way out.
Simply creating a 4.5 context will not trigger the bug, haven't been able to
fully test what causes the hang specifically as accessible tools I've found are
not compatible with mesa due to only creating a default context (which is
currently 3.0), thus crashing on init.
