Unity UI Pixel Perfect Canvas A Killer!

Pixel perfect mode on a canvas can be a killer for frame rates, particularly in a long scrolling list.
I feel like it should be auto disabled on scrolling lists or something as enabling it can destroy your frame rate to such an extent!

Perhaps it is never needed on a UI canvas but I think on desktop/standalone (non-4k) it is still helpful to give a crisper render and with text you have to do everything possible to get it sharp!
