i'm having a "framerate" problem with a script on a website i'm building:
When the browser window is on the external screen (an apple led display), the animations works perfectly fine, but when i pull the same window on my laptop screen, the animations are awfully slow (about 1 fps).
My conputer is a brand new macBookPro, with a 13 inch retina display and a very good configuration, the screen settings are set (for both screens) on "optimised for the screen".
The mouse cursor, scroll or any other animation on the (default/retina) screen seems to work normally, so i would say it is not a refresh problem of the whole screen.
I cant figure out why this happens, or think of a method to find out, so i would be grateful for any kind of advice (or solution).
Thank you for your help.
