Replay Mod Forums

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

Please help! Thanks

How about when you hide the GUI by pressing F1?
If it's the same, then try asking on the OF issue tracker.

When I press F1, the same thing happens..
Also, I'm not sure what the OF issue tracker is, could you possibly link me it for me?

Oh, with "OF" I meant Optifine. It's a common abreviation and I usually write out Optifine once before I use it but I appear to have forgotten about that in this thread.
It lives at https://github.com/sp614x/optifine/issues
