#22 shows an identical render issue but it was assumed it was an issue with TFC+. I just loaded triangulators with vanilla minecraft and it seems like minecraft ice and stained glass have this rendering issue with water.

This is a known vanilla bug: MC-91224.
I will look into fixing this in the future, but for now it's low priority.

Added a workaround in 2.0 Alpha 3. The Z fighting is still present, but now it's consistent across the entire quads, so it's not that visible.

@facetorched is it working properly for you now?

Yes it seems to be fixed after upgrading to falsetweaks-mc1.7.10-2.0.0-alpha0005, falsepatternlib-mc1.7.10-0.10.11, 00gasstation-mc1.7.10-0.3.5

Had to remove archaicfix from my mods folder for it to launch though. Haven't had the time to test exactly what the cause and if I do i will open an issue.
