Description
Animations such as those on
.wpview-loading ins
cause high cpu (>50percent of one on my i5)
If I replace "linear" with, say, "steps(12)" it goes down to a reasonable cpu load.

12 steps seems too choppy. Tried 36 and shortening the ins a bit. That reduced the CPU usage here by more than half: was 8-9 now is 3-4, GPU at 1-2 as reported by Chrome's task manager, 5 years old i5).
