Additional Information

This issues just started a few days ago because I've played Minecraft with Sodium since the release and suddenly this happened.
I don't know what caused this because I Didn't use any other mods expect for sodium. My performance was good when using this but without this my game lags a lot.

Duplicate of #219
Workaround: delete the sodium-options.json file from your game's config folder.
