There appears to be order of magnitude (from 0000015:0000015 ms/frame to 0000118:0000150 ms/frame) degradation in slice scrolling performance when volume rendering is enabled (slice is not shown in 3d view).

This was done on a mac with the latest nightly.

Problem is reproducible on Windows and using Qt5, too.
