Well, the notorious full screen animation has been with OS X for quite some while now. There are many discussions around it yet no solution seems to be found.

Here are two for example:

Most popular "solutions" are two:

> NSAutomaticWindowAnimationsEnabled -bool NO"

> Hit enter

**In reality, NSAutomaticWindowAnimationsEnabled doesn't effect OS X 10.9 at all. Nothing will change however you like to set it.**

**In reality, Total Space can disable some animation switching between screens, but when you play a video on, say Yahoo Screen, the animation from a small video to a full screen video still remains - and in fact that is the actually annoying animation (takes about 0.5 second to complete therefore breaks the video experience).**

I am shocked that there is still no solution to this problem! Perhaps someone can discover a hack around this? If you do, I am happy to make a free OSX app to enable this option for everybody.
