Description

everytime I use voxy I chunks start to flick. I think that's because of something with my video drivers or smth because my friend with Nvidia card don't have any issues like that. and I have. my specs:
CPU: Intel Core i5-8350U
GPU: Intel UHD Graphics 620
Minecraft 1.21.11
Voxy 0.2.13
and while LOD chunks are on screen FPS drops to around 30 despite I have around 100 FPS without Voxy (voxy render distance doesn't matter, with 20 chunks or with 130 FPS drops every time)
there's video of flickering chunks:

Research direction

Start by reproducing the flickering and FPS drop with Minecraft 1.21.11, Voxy 0.2.13, and the reported Intel UHD Graphics 620 setup. Compare behavior with LOD chunks enabled at different render distances and inspect the attached video; done means identifying a reproducible cause or confirming whether the issue is specific to the Intel driver path.
