opt_uniform_atomics causing problems on RT shaders & OpenCL kernels
Disabled for RT here : !16104 (merged)
We're also having issues with Gfx7/7.5.
Somewhat related, this was found to affect this FarCry rendering issue for me : #6420 (comment 1405082) For @kwg that didn't completely fix it. Seems like we might have a backend issue somewhere.
