That's...interesting. I have a second monitor running Photoshop, and images from the second monitor (perhaps just from Photoshop) are being mapped onto the model of El Capitan, making the visual completely broken. This occurs in Firefox, Chrome, and Safari (using OS X, if it's not clear). This does not fill me with warm and fuzzy feelings. :)
