Also, I just updated from nightly 20160816 to 20160827 to try to avoid screen problems like the attached that just started happening today

shot of this screen amazingly has data from two different pages

I think this is one instance of the recent igd10umd64.dll crashes, aka bug 1295075 and bug 1292923 It looks like you can reproduce it locally. Maybe you can provide more information there, it will be very helpful.
