Yesterday I released a new update to my playerbase, test went well, until I released to a 100% of players
This is the bug in question: Imgur: The magic of the Internet
The bug appears to happen to around 2-3% of players, which adds up to around 30k players.
The issue seems to be device specific, and seems to mostly happen to older phones.

With a lot of messing around, we managed to get the terrain shader working by removing āout depthā, however that did not seem to work for the part shader.
Any help would be really appreciated, iām getting absolutely spammed with reports of this bug.
