Describe the bug
The graphics turn weird in one corner on the facades. Screenshot below.

To Reproduce
I tried it with Optifine HD E3 Ultra (on my other saves the glitch doesn't seem to pop out, even with OptiFine). Place a smart cable and a facade on it, and it should glitch like that.

Expected behavior
I expected the facade to blend into the marble/glowstone (using the CTM mod). It only blends 3/4 the way and the last quarter just keeps glitching out.

Additional context

GPU: AMD Radeon R9 270X Series (not overclocked)
CPU: Intel i5-4400 3.10GHz

Environment

• Minecraft Version: 1.12.2
• AE2 Version: rv6-stable-6
• Forge Version: 14.23.5.2837

Have the same problem

CPU: FX-4350(4.5 Ghz/Overclocked)

RAM: 16 Gb 1720(1600) Mhz.

Are facade part of AE2 thought it was an add-on

Probably some optifine issue. They constantly come up in various combination.

Looksl like a chisel block texture due to the 2x2 texture grid. So could be something like CTM + Optifine not working in some cases or for some blocks.
