Glitiching - 1.9

When playing in the game and if you decide to jump from a tall object ( Don't know how tall it has to be) or if you fly in creative mode, and then change into surrvival mode, and just before you hit the ground, and press the ESC (Escape button) then you save the game and quit, strange glitiching occurs. It will affect other saves too but it doesn't do any damage it just you're not able to see the area around you. The only way I know how to fix it is to relaunch Minecraft. But it will happen again if you repeat the steps. 🙂
