Glitchy textures after upgrading to 3.6

See original GitHub issue

What I did / Steps to reproduce

I upgraded an existing BlueMap installation from 3.5 to 3.6 by replacing the BlueMap jar and deleting bluemap/web/index.html. I upgraded PaperMC from 1.19.2-271 to 1.19.2-287 at the same time in case that’s relevant.

Expected result

I expected the map to stay effectively unchanged.

Actual result

I get glitchy textures in the area of high LoD:

Perspective view Free flight view

The map is available here.

Context

BlueMap Version: BlueMap-3.6-spigot BlueMapOfflinePlayerMarkers version: 2.0.1 Platform: paper-1.19.2-287 on Linux
