I've installed Ubuntu MATE 18.04 and want to get the thumbnail window previews when hovering over applications in the bottom panel. The option appears to be on:

I seem to get a flash of what might be a preview for a fraction of a second on an initial hover sometimes but it's really hard to tell as it disappears more or less immediately when it happens.
How should I go about debugging/fixing this?
