Is compositing in OCIO broken?

Because it’s actually impossible to comp anything with highlights without them becoming inverted. These invalited pixels you are seeing here are only 1.100-1.500. They are not overly bright yet this happens. It’s a joke. Stop messing about without AI crap and fix the basics. This just a white line being screen over the top of my CG. It could not get any more simple. Adobe, you are a joke.
