Hello! It's weird because when I tested it on my Mac there was no problem at all (Macbook Pro 15" End 2013 with macOS Sierra). But thanks for your observation, we will investigate on that!
I figured out how to work around these kinds of bugs. If you hear music and SFX that responds to your movement but see only black or pink, try ESC then Options and reducing the Quality or Resolution sizes. Play around with those whenever a problem, Apply then Resume game. Sensitivity tweaking helps too depending on your mouse. It worked for me!
