I am also noticing some odd behavior on my mid tier 2016 with the AMD 455. It's not the same issue as the multicolored graphical glitches above, but using Safari things would freeze, disappear from screen, web pages would not load, items would arrange in weird layouts or just not load. General bugginess all around. I think it got worse when it got warm using google street view. I've also noticed that the four finger drag freezes quite often, along with general UI lag.
And another oddity - I've lost about 50% of my icons in the both the applications folder and the dock, replaced with the default paper, pencil and ruler icon. Very strange. Happened just after I had all the strange behavior noted above. I don't have any Adobe applications installed.
I'm planning to replace this machine anyway as the screen has very bad white point variation - cool blue on the left side, white in the middle and blue again on the left. I plan to take the opportunity to reluctantly upgrade to a 460 as I need a Mac for software development but I'm close to considering the non-touchbar as that doesn't appear to be plagued with all these issues. The 15 inch does feel like an alpha release to me.
