Should I bug report this?

I have this annoying bug where I don’t see entities (besides custom models)…
I’m forced to turn on hitboxes to see where they are cuz I only see the name trash or some parts of the mobs that are custom-modeled…
It’s really annoying and gets really laggy in raids…
Is it cuz I hav a shit pc and that my graphics card is outdated, or is it a bug with the texture pack?
I didn’t see anything about this sort of bug so I think it’s just me…
