I can see both at the same time, and switch between different modes at will. I also tend to be immune to or see much more clearly all kinds of optical illusions and visual effects like this at various at will, or see them all the different possible ways simultaneously, able to see intuitively why things like this works, separately see "colours" like "movement speed" and "local contrast" in a way that intuitively feels like they were sent from the eyes as separate from maps of those properties that have more a feel of concious deduction and are immune to many common optical illusions, am ascribed a good aesthetic sense and artistic talent, tend to move my eyes and scroll on displays in ways that others find disturbing or even painful but I feel constrained and tunnel visioned if I try not to, I have occupationally experienced something reminiscent of blindishgt for short periods of time (remicent in the same sense as a polar opposite is), and am able to "see" things other's can't, and a bunch of other related superpowers.

Hope this is interesting enough as a case study to not come of as bragging. Feel free to run experiments on me since i love this kind of thing.
