10 hates anything more than 100% even on a single display layout
7 handles scaling better even micro adjustments like 110-115% which is perfect for me.

10 just changes those two examples to 150-175% and borks it up even though one chose a # way lower.
It's been that way since the beginning that I recall.

I turn off auto snap a long long time ago it was more a pain than a useful feature.
