How to show Google map on the modal bootstrap?

Why does google map show one part of the map and another?

• Hi! The question may be a bit confusing but basically what happens is when I use google Earth, the whole map im movable at first but as soon as I touch it, only a small part of it is movable. It's like seeing the map perfectly fine through a screen... This is not lag as I've tried waiting for it to move by leaving it on for a whole hour but part of the map always doesn't move. Here's more info, hope it helps. Sometimes when I play games the game screen suddenly shrinks, leaving space that was mean for the game to be there. Skype messages are also tiny, even if the screen is full! When I visit websites, most of them show the page ccenteredon my screen, navigatable and everything but it looks as if it's shrunk... Thanks!
