With driver 126.96.36.19914 several tests failed: https://clbenchmark.com/result-details.jsp?id=137702391623988882
Today Intel released a new driver and exactly 3 months later still not working properly. It's clear Intel doesn't care. I won't bother you anymore with bugs I promise you.
I am sorry you are disappointed. We do take these issues seriously. The optical flow test was debugged (a while back) and was determined as a test case issue. I will take a look and escalate these issues asap.
Optical flow and all other tests worked fine with 15.31.
All the four tests fail with clCreateProgramWithBinary() returning CL_BUILD_PROGRAM_FAILURE. I will debug this further, but is it possible to share the .cl files or are they proprietery?
