When you turn anostroptic filtering on, the contents of the pipes become weird:
Fuel looks like fire,
Oil looks like fuel,
Water turns brown,
Energy becomes a weird yellow lines with green squares

Fixed this, forgot to close.

Are you using optifine?

Nope, just the mods shown :)

Cool bug. :))

@ganymedes01 - Could you take a look at this?

That's bizarre lol
But yeah I'll see what I can do

It is problem when you turn filtering on or off after load. It probably causes some shifts in atlases and de-synchronizes IIcons.
I have no idea why it is happening (it does no happen always) and it affects probably not only BC.

I can't reproduce it
Loaded a world with it off, turned it on, and the icons still look normal.
