Description of the bug:
Alpha Divide can cause infinite values when set to GPU mode or Auto (which means using GPU by default).
This will cause fringing to appear on edges pretty much meaning an unusable image unless you don't care about broken images.
CPU only is a workaround.
Blackmagic support was not able to replicate this issue, but I believe @Midgardsormr mentioned that he was affected as well. Maybe this is Cuda/windows only?
In my case, the render is coming from Mantra.
I have attached a file and comp to verify this.
BLMD asked me to do a clean install of my drivers, but not once in my life did that fix anything for me, so it would be great if somebody could help me verify if this is windows/cuda/NVIDIA only, or if it's a "me" problem again.
Severity (Trivial, Minor, Major, Critical)
Major, as GPU is the default.
Steps to reproduce:
Download the files I provided to test of if there are infinite values after the Alpha Multiply.
Please, if possible, provide a Fusion setup to help demonstrate the behaviour, either as an attachment or between
see attachment as it requires an image file
