So i was trying to use Vic's MW mod with shaders, (any shader, Seus,continuum, bsl, even the internal one) i put makes the screen small when i aim, im using OptiFine HD_U_F5 and lastest versión for vic's (mw_2.0-0.4.4.6_mc1.12.2). This happens:

any way to fix it? also ram has nothing to do probably but i allocated 10GB just so u can check things out xd. i had to press t to do a screenshot or by pressing f2 it crashes while aiming, also when you stop aiming it goes back to normal in a couple seconds

1.12 is no longer supported on this forum. Please update to a modern version of Minecraft to receive support.
