Macbook Pro - video choppy

Not a huge issue, but I've noticed since 4.0.0 through 4.0.4 that the waveform displays are choppy on my Macbook Pro. I'm running yosemite on a 2.4Ghz i5. As far as I know my model does nt have a separate GPU and uses the chipset video card.  My waveforms are smooth on Traktor and SErato but seem to be a little jumpy on RB.

I've adjusted latency from lowest to 20ms and no change.  Also zooming out or all the way in doesn't seem to change it. I've also changed the setting for waveform performance from low to medium to high and haven't really noticed a change.

Anyone else experiencing this?
