Looks like the same issue as #36669

Funny enough, that one appears on Windows, not just Android and iOS.

Yeah I do think it is a similar issue, when I applied the fix in the other issue the tree now renders if there is nothing behind it. However, there are still some issues with the leaves of the tree having a hard time rendering in front of each other. My normals are correct and cull is disabled, this only happens on opaque-prepass on the device itself.

EDIT: actually I can get the same results in on the computer if I mess with the no-depth test. I have my project settings to enable depth pre-pass. (if that would affect it)

Here's a new screen of the fix in the full app not just the minimal project.

Probably fixed by #50721.
