Description of the issue:

Hi. While connecting to a private server, I noticed that the IE blocks have become invisible (They are still there, but they are transparent)
The cables remain visible

Versions & Modlist

IE : 1.18.1-7.1.0-145
Forge : 1.18.1 - 39.1.0
Create : 1.18.1_v0.4d
flywheel : 1.18-0.6.0
radium : 0.7.7g
rubidium : 0.5.0

Does this also happen without rubidium?

Also experiencing this, only happens with Rubidium.
