OpenCL causes glitches in Hybrido on my GTX 980 Ti

When I run this Hybrido simulation project in RealFlow 2014 using OpenCL on my GTX 980 Ti, I get terrible streaky artifacts as seen here.
Before, on my previous GTX 580 I never had any problems like this.

I'm running the latest drivers (353.06) from the NVIDIA website on Windows 8.1 x64.

When I turn off OpenCL in the simulation settings, it takes much longer to simulate but the result is clean as expected, without any of the streaks:
