Possible Incompatability causing texture bugs.

What happened?

When enabling Iris in my modpack certain textures will break and turn into lines, but not the missing texture. The textures affected can change based upon what resource packs from mods are loaded and which aren't (Nothing important, just things like alternative textures offered by mods)

Additional context

Not sure what could be the issue here. I'm guessing it's conflicting with another performance mod. Going to go through and try to figure out what's going on.

This bug is known already and will be fixed in iris 1.4.1

What's causing it if I might ask?

Quoting Coderbot's message from the devlog channel of the Discord server: "This issue was caused by an oversight in Sodium that was over a year and a half old. It caused textures placed on the edge of the texture atlas (in this case, the still water texture) to have some of their texture coordinates wrap all the way around to zero. That's why the bottom of this water looks like a bunch of stripes - it's about 32 different Minecraft textures smooshed together!

This only occurred in very rare circumstances with specific combinations of resource packs and mods. Iris 1.2.5 added an optimization by Pepper to make the Minecraft texture atlas more compact, which made this issue way more likely. Thanks to a straightforward way of reproducing the issue with just Iris and Sodium provided by Deebz96, it's finally been fixed!"

Oh that's awesome, sorry for the spam then. Is there a release window. Also feel free to close this if you can. If not I'll close it tonight.
