Hello, i have noticed some very bad color problems when using Karma XPU vs CPU. I am not sure what exactly causes the issue but i think it is either metal calculations or something with specular, as it happens both when applying coat and with certain metal colors (orange is very noticeably green, but it happens with other colors too, like red in the attached images.)

I have already sent in an rfe, as i think it must be a bug, but i wanted to ask if anyone has seen this before and maybe has a solution/hack/explanation?

I saw a post that it's related to nVidia's drivers. Perhaps try an update...
