I haven't been able to figure out the hang. Some observations though .. I've
disabled EXT_tessellation_shader in the driver, this causes antutu to jump over
the first test and run rest of the tests and there is no hang. I've also tried
disabling usage of push constants (hang seems to be related to these) but this
did not help, hang still occurs. Next thing I'm going to try is to dump all
shaders from first test and see if I could figure out which ones might be
related to the hang.
