Timeline Indicator Problem

In todays build, on a multicam sequence, the timeline indicator is not moving smoothly. It stays where I start playback, then jumps to where I stop.  If I'm looking at a still, I'm not sure if it's playing or not.

Timeline counter (time display) also freezes during playback.

Haven't restarted yet...
