You cannot set the blurKernels to 0 as this is considered by the system like turning off the feature:

Also found a new problem, if you turn up the adaptiveBlurKernel, the scene stutters!  
at code line 81 and line 84  
I need your help!

Not seeing any stutter, what device are you testing it on ? this parameter is not meant to be that dynamic as it forces shader compilation incurring quite some perf cost.
