Waveform Window Blanks during Scrolling

Running Mac OS X 10.10.4, and using Audacity v2.1.1. I notice that the waveform window goes completely white when dragging to scrolling horizontally (as you would to find the beginning or end of a track). It redraws when I stop the horizontal motion. Anyone else seeing this? It makes it just a tiny bit more difficult to find the spot(s) I’m looking for.

Anyone else seeing this…?

No I don’t see that. There are other ways to scroll longer distances such as SHIFT + comma (backwards) and SHIFT + period (forwards) - those work whether playing audio or not - or Scrubbing and Seeking.
