I just updated from Chisel 0.0.10.22 to 0.0.11.25 and I get this weird visual bug with EnderIO painted conduit facades and painted glowstone. Ender IO version hasn't changed (still 3.1.192).

Both blocks were painted with "Marble | Circular | Has CTM"

Modpack: https://minecraft.curseforge.com/projects/cjs-modpack (v1.7.7 to v1.8.0)

This is multiplayer

Fixed in EIO

Nope. Your bug. SleepyTrousers/EnderIO-1.5-1.12#4261

It seems that the glowstone thinks it is connecting to the other blocks (as you see it looks like the other center blocks) but the chisel blocks don't recognize it.
