Issue description:
Using any shader (with optifine) will result in a graphical issue with the projector.
with shaders turned off everything appears fine.

Steps to reproduce:

1. Enable shader
2. Look at a projection

Versions:

• Minecraft: 12.2
• Forge: 1.12.2-14.23.5.2847
• McJtyLib: 1.12-3.5.4
• RFTools: 1.12-7.72
• optifine: 1.12.2_HD_U_E3

I also get the error: "could not find component 'offset'!" when i open the scanner gui.
I also get the error: "could not find value 'rsmode' in supplied TE!" when i open the locator gui.
I dont think its related tho. This error is both with and without shaders.

edit: I tried multiple shaders, all the same.

Can you report this to OptiFine's tracker? Since their developers can see our code but we can't see theirs (RFTools is open source but OptiFine isn't), they're much more able to debug these sorts of things.

Will do,
I will keep you updated.
Thank you for your time.
