I can't tell if this affects Beta 1.8 or not, wanted to see if this was a new iaaue or whether it's been here since the introduction of smooth lighting.

Can you reproduce this bug in 1.16 pre release 5?

Yes, I can.

If a bug upon its introduction with lighting ice is anything to go by, this bug goes as far back as Beta 1.3...

Mateus Pereira Milbradt don't pretend to be a bot

I've been able to screenshot this on a old version of Minecraft (beta 1.7.3) so it would be safe to assume this bug has been here since Beta 1.3...

It's outrageous to realize that this bug has been here since Beta. If you're a programmer you can tell that Minecraft's source code is so f*cked up. As a developer, I would have no interest in fixing such sh*t, but there is a guy who works on these rendering bugs and it seems he doesn't care about improving Minecraft's visuals!

simply not converting quads to tris at the tessellation stage fixes the problem

This is me using quads with my smooth lighting port to Alpha v1.2.6:

Therefore, there's no need for any custom interpolators as the GPU can handle it on its own just fine.

oh and @MotanGish, they have better things to be doing than fixing issues caused by janky interpolation done on triangles by practically every GPU in existence

Can confirm in 21w40a.
