Description / steps to reproduce

There is Currently a bug where things like the Bow and all other tools invisible for my self and for other player in the Hotbar they are invisible too and when hold only the holding Person is seing them while other people or in F5 theire appearing Invisible

Sorry for my English

This is a known issue when using certain performance mods e.g. Rubidium, (I think Rubidium is one of them? idk they have so many names these days)
I do need to investigate this issue, but I'm not sure if there is anything I can do on my end to resolve this.
If you are using a performance mod, can you please check if removing it resolves the issue? And also let me know which performance mod you are using.

It seams that the mod Immediatly fast is one of the main Culprits
Iris shader with monocle and Embbedium are working as soon as shaders are on the core looks like the core from 1.12 but the tools have an working texture
