I have run into this problem and its actually a really easy fix. the problem is jquery mobile has the css rule
- .ui-mobile img{
- max-width:100%;
- }
This interferes with the google maps image sprites as they are larger then 100% width. so to fix it simply add this rule to your css
#mapID img{
max-width:none;
}
just replace #mapID with the actual id of your map
