Every time I turn my shaders on, it works perfectly fine in game when I use it. However, whenever I replay the footage, the screen turns completely red and black. (Mostly black, but if I shift my mouse to a certain angle I can only see bright red). If I leave the replay, my menu tab turns red.
I am using 1.8.9
