GMAP bubbles background broken

I've installed GMAP on 2 separate D7 sites and am experiencing broken backgrounds to the bubbles (see attached file). These are both pages from a view (export below). Both sites are sub themes of Omega but I've switched themes to Bartick and have the same display errors.

I've looked for any offending CSS but can't find anything that's affecting .gmap-pop up that would cause such things.

Is anyone else experiencing this?

Currently bubbles aren't useable for me in this state (though everything else seems to be working well).
