Weird Frame rendering

Put the summary of the bug you're having here

What I expected to happen was...:
to see the same frame on the entire screen

What actually happened was...:
/ while falling from a height i noticed a slice from the top left corner to the right bottom corner , like if it was in between two seperate render engines , so on the one side there was different frame than the other side
/ looked pretty weird.
/ i tested it on another monitor , same thing.
/ after some tries the bug stops , but reappears when you move some blocks further

Steps to Reproduce:
1. get on a pc win 10 , mc 1.8.8. , get in a creative world
2. fly near by a tall object towards up and then fall down by double tapping ' space'
3. look at the top left corner while falling
