I had this problem yesterday, with more than just the tinting -- screen blanking completely, screen shake. It went away completely, I'm not sure why. System is completely updated, but that was the first thing I did, so that's not it. It also wasn't turning the auto-brightness off.
Now, it's come back. Completely. It's totally reproducible: anytime a video or animated gif scrolls into view, screen hue changes. What's worse is that I now also have intermittent screen blanking outside of Edge. I've had it happen on the log-in screen and on an empty desktop. The tinting issue is clearly a software issue: it's so predictable. My money is on the graphics driver: brand-new chip and all that. But the random blanking concerns me much more.
