Toru the Red Fox

Another issue is the fact that Alpha doesn't get patched correctly due to incorrect flags in the JSON files which leads to your name always being Playern (where n is a random number, or a hardcoded number depending on the version) (see MCL-18826)

still present in 1.17, but not to the same extent
the game also tends to cause huge system-wide stutters on certain hardware when starting up

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

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.

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

isn't that caused by lighting?

I'm fairly sure this is 100% intentional as it's been like this for 10 years now

entities have no smooth lighting, only blocks.
