It appears you are using a lot of mods. Please try with only Immersive Portals. dependencies and rubidium/occulus and see if the issue persists.

well i moved on to 1.21.1 neo. which has its own problems. i think i did only Immersive Portals. dependencies and rubidium/occulus b4 n still had that issue. i just abandoned that build. It was only when shaders where active. if i used the hot key to disable the shader it would show as intended. it might still persist on 1.21.1 but idk as im busy figuring out other mod incompats.i might retry it in a few days and come back with findings
