I don't know if this is related to the WebGL changes, but the contrast and saturation is a few procent higher in [R107] than it was in prevoius releases.
I am using a monitor calibrated for photo work and the change is very obvious to me. I have to say I like the change as is gives a much clearer image and less washed out colours. I hope this is intended.
(btw. Ashley, the animation problems are completely gone in R107 - I don't know what you did different from 106 to 107, but it sure worked!).
