System Information
Operating system: Darwin-18.7.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon Pro 570 OpenGL Engine ATI Technologies Inc. 4.1 ATI-2.11.20

Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-24 14:22, hash: 507ffee6e1
Worked: (optional)

Short description of error
setting noise step to 6 should update the noise value every 6 frame. In render this value is ignored and updated (seemingly interpolated) each frame.

Exact steps for others to reproduce the error
open the attached blend file and play the animation in viewport. The noise on the stroke will be updated correctly. Then render the sequence and look at the result.

@antoniov after applying your patch the interpolation is gone but the noise still behaves very different from viewport and render. In render seems to just pop to the same noise value each step and then pop back to no noise value.
Can you please compare viewport and video render output to check if this is working as intended?

viewport:
testnoiseview.mov

render output:
testnoiserender.mp4
