Something I noticed after downloading this is that there are some weird artifacts near the horizon of my superflat world. I checked on a regular world, and I didn't see the same artifacts, which leads me to believe that the issue might be with textures that are on the same plane. Either that or the artifacts are just too subtle to notice anywhere other than a superflat world.

This mod doesn't work on all systems. It removes a workaround for the issue that you just mentioned which is called atlas bleeding where textures nearby in the atlas bleed into eachother at a distance. For me this is not an issue and I haven't heard of other people having this except for some that were using a Mac. You might want to remove the mod

Damn... in that case I'll just hope Item Model Fix updates to 1.19.3 soon lol

You can try to tweak the configs until you find a set of values that work for you
