I use the Google Maps API (v.3) to show a map with a couple of markers. I recently noticed that the control used to zoom the map is messed up (it wasn\'t always like this).
#myMap_canvas img {
max-width: none;
}
fixed it for me, but I also wanted to point out the comment on the question by @Ben, "This issue doesn't happen with Bootstrap if you use the is map_canvas as the map div id". He's right. I'm not using Bootstrap, but the problem started happening after I changed the div id.
Setting it back to map_canvas fixed it without the max-width change.
