go to project settings and check if you are utilizing the GPU for effects. If so, turn off (software only) and check again.
Thanks Roei, that's fixed it and now I feel like a dumbo for not spotting that sooner. Woo!
Just for future reference, I've read through the GPU doc, I'm guessing I wasn't gaining anything by having GPU enabled anyway? I'm compositing 2D animations in Classic 3D workspace, with a few effects on solids/shape layers (often multiple of these stacked as comps within one another). Just want to make sure that if I turn it off, I can leave it off for good so I don't run into any more issues, else I'll take note just for this project!

fractal noise is a new addition to the GPU accelerated family as of CC2017. apparently something through the processing of this effect with GPU is not working right in your system. maybe on any other system as well, can't be sure. you should provide a bug report here: Feature Request/Bug Report Form
if it were to work on the GPU, it would render faster - you do want to use it if you can.
these are the effects so far that are accelerated by the GPU if the option exists in the project settings:
- Gaussian Blur
- Lumetri Color
- Brightness and Contrast
- Find Edges
- Drop Shadow
- Fast Box Blur (formerly Box Blur)
- Fractal Noise
- Gradient Ramp
- Levels, Levels (Individual Controls)
It's possible that turning your project to 16-bit or 32-bit would also have fixed the issue.
I've noticed a HUGE difference in speed when Fractal Noise is set to use the GPU.
I just tried changing the depth to 16/32bit with GPU enabled and it still does the same thing sadly
I've filed this as a bug report. I know it's a bit of an awkward use case but glad it still works as it should without GPU for now… While my GPU gently weeps!
I realize this post is almost a year old, but I ran into this very same issue while trying to follow along to a Video Copilot tutorial. I'll submit to the Feature/Bug report as well, but wanted to pop in and ask if this had been resolved to where the GPU could be used again.
Aye, still an issue. The fix for now is to disable GPU rendering in Project Settings, which sucks because there's a real noticeable performance boost compared to software rendering. But this also ensures it renders out perfectly, as is, and previews properly too.
One more thing to mention is that despite setting software rendering in AE, Media Encoder or Premiere, the bug persists in Media Encoder and Premiere regardless of rendering/playback settings. Solution for now is to bounce the project down to a MOV from AE only, which can be a chore for beefy projects.
Thanks Roei, but sadly setting project to 32-bpc still doesn't resolve this for me. Software/CPU renderer works fine.
Please file a Bug Report.
