I started implementing my software using maps api v3. Unfortunatelly i found out that v3 API has some serious issues which draws me back from bying a bussiness licence.
We had issue that we had CSS3 transition added to all elements..
So remove transition and its worked fine..
See example:
#map * { -moz-transition: none; -webkit-transition: none; -o-transition: all 0s ease; transition: none; }
