Entities, items, and players flicker when using iris shaders+shadows with Physics Mod

[wackiestwow]

What happened?

Whenever I turn on shadows using shaders (bsl, complementary, and sildurs were all tested), entities, items, and players flicker in and out of existence. This is a major drawback in my survival worlds because chests and anything else that is considered an entity is affected. When I use optifine, the shadows work fine. (took me a while to get good screenshots, as it is a very fast flickering)

Steps:

1: turn on sodium and iris

2: turn on shaders

3: enable shadows

4: travel around, and artifacts appear

Does this happen with no other mods installed? If so, does this happen with Iris 1.1.3?

i never thought of it being a conflicting mod, when i removed everything except sodium and iris, it worked fine. It looks like the entity culling or the optimized lighting mods were conflicting. thanks for opening my eyes! (sorry if i wasted your time XD)

update: it seems physics mod was the issue

I assume that this issue is caused by my mod as well. It basically thinks it has the right buffers bound right in this function: BufferUploader.updateVertexSetup which it doesn't have anymore. Seems like a bad practice from Mojang though when there is the GlStateManager._glBindBuffer function which can be called from anywhere else and it doesn't update the local variables of BufferUploader.
