If you use a shader, and then click F5. Your shader will disappear . And when you go back in to first-person mode. its also gone. Before I posted this. I tested if this also happened with other Shaders and it did. I think this has to do with a feature in spectate mode.

Same thing happens when you use the cinematic camera, but when you turn off the cinematic camera, the shader comes back.

Actually, this has been the intended behavior per Mog from MC-46563:
Fixed, I made the game turn off the shader when in third-person mode and spectating a mob. I also made F4 into a toggle rather than an instant-off.
Confirmed.
