I applied this patch additionally to the revert: <a class="bz_bug_link bz_status_ASSIGNED " title="ASSIGNED --- - Unreal Engine 4 demos fail GLSL compiler assertion" href="show_bug.cgi?id=80880#c10">https://bugs.freedesktop.org/show_bug.cgi?id=80880#c10</a> Many demos work now. But the Cave Demo does not work, it hangs the GPU. I can not reproduce the original bug I posted here anymore with the patch, just the hang. It looks like this: ring 0 stalled for more than 10146msec GPU lockup (waiting for 0x000000000000a921 last fence id 0x000000000000a920 on ring 0) failed to get a new IB (-35) Saved 205 dwords of commands on ring 0.
