Just to make sure I'm understanding right, I think you're actually talking about the horizontal scrollbar? (ie: for scrolling left or right in time).
So what seems to be happening is that the range of the scrollbar isn't getting set correctly. It has a slider, but it's full width because there's no range of movement available.
We set up the slider range in updateView based on the sample count and zoom/fft levels. It seems like in the 'bad' log, there's no updateView call after the WindowActivate event, so maybe the sliders end up just having default settings until some action triggers updateView to fix it.

You are of course correct: I meant the horizontal scrollbar...

This patch solved the issue for me. It feels like a hack, though:
