Disableing a track does not hide track while scrubbing

[zaphodikus]

1 add image to main track
2 Add a few images to overlay tracks , add custom motion to them all, stack them so they are all visible
3 click the video icon to disable the tracks but not the main track
4. scrub on the timeline and expect to always only see your main track without the overlays.

The disabled overlay layers intermittently will appear in the preview whenever you let go of the scrubber, it's a bit maddening?

Anyone else see this happening? Or is it just because I'm a software tester, that unusual software behaviours are attracted to me?
(Does not always happen, but it's the 3rd or 4th time I had it happen - seems to require you have motion distortion of the pictures)

My images on the Disabled overlay tracks disappear when playing or scrubbing the timelines but show when paused / stop playing

Interesting, odd, if I disable the overlay track then apply Customise Motion the effect does not show, works as expected....
But first add Customise Motion then disable the tracks and the images show when playback paused
