Perfect, thanks! (And bizarre!) PS: you can drag the top edge of the timeline panel higher to make it taller when taking screenshots.
Ummm.
It kinda looks blank for the vizemes! But you say during playback they move? Ummm.
How about trying to zoom in so you can focus on a shorter time range. There is the slide bar in the bottom right corner to change zoom factor. If you zoom into say 10 seconds, do the vizemes start appearing? Just wondering if the zoom factor is causing it to "give up" on rendering. Ah, yes, it seems if the vizeme gets too narrow, it diappears! So zoom in. This is 7 seconds across the window - they are clear then.

When I zoom out the same track, they vanish!

Also looks like there are two vizeme tracks (one recording/masking the other). This is not wrong, just looking for anything unusual at this stage.
