**System Information**
Win 7, R9 280X with Radeon Software 16.1.1
**Blender Version**
Broken: 2.77
Worked: 2.76b
**Short description of error**
Some shaders like water will not render correctly any more
**Exact steps for others to reproduce the error**
Open Pabelon Barcelona scene from the cycles benchmark suite with 2.76b and 2.77, switch to "GPU Benchmark" scene, hit F12, you get this:
2.76b, correct:
{F286687}
2.77b not correct:
{F286686}
Note that it's the exact same scene, the change in trees/flowers position is due to broken particle system (by the way, it would be good to remove any multithreading to make it more stable, because the new system is not coming in a foreseeable future?)
