Just got the Anniversary Update last week and I noticed an issue I was having with Windows Photos was corrected (missing next/prev arrows). However now if I have a large photo open in the preview window Photos is using 30% CPU usage. It's causing my SurfaceBook i7 fan to sound like it's prepping for take off.

This seems like an excessive amount of CPU usage just for having a high res (3264 x 2448) photo open in preview mode. Am I right to think that? I don't remember having this issue pre-update.
