I have the same issue

Does your friend use the Optifine mod? If so, don't use the Optifine, and use the newest Rubidium+Oculus instead, since Optifine has made tons of bugs and conflicts with other mods.

@W-lxrd your picture is crashed. Need updates. Also bring the modlist that you install (use Pastebin or Gist), so that I can find out which mod cause this problem.

Installed mods(1.16.5): Obfuscate 0.6.3, cmg-1.2.6

Issue: long and medium scope don't work(all white)
Just the small scope works
Launcher:pojav launcher
(mobile)

Tanks for attention :)

It seems that you didn't list all of the mods. Therefore I can only guess it's OptiFine (or other shade mod) that made this error. Uninstall OptiFine, since OptiFine has made tons of bugs and conflicts with other mods.

Helo,there is no mod installed, and minecraft graphics settings are almost default
I don't what is happening
See

The mods folder open and with the game

Seems strange, since these bugs usually comes with shade mods. Do you play with Bedrock Edition, not Java Edition?
