Basically what the thread title says - I'm working on a fairly large map (64x40 squares with .5 grid size, two separate map images placed side by side) and whenever I zoom in to 80+% zoom the background map disappears completely, leaving nothing but a blank white slate with a grid and player tokens on it. This happens both in regular view and in gm-as-player view. The problem seems to be Chrome-specific, Firefox works fine in all zoom distances. I'm currently using Chrome 27.0.1453.116 m. In case anyone wants to take a look at it the map in question is called "The Hook", and is the page the player's flag is currently on.
