rubidium-0.6.2b
rubidium_extras-1.19.2_v1.4.3
ImmersiveEngineering-1.19.2-9.2.2-165

Doesn't happen every time, doesn't even happen often. I just got this for the first time, and it didn't happen the next launch.

It's a game rendering thing, and the crash report mentions Rubidium, so I assumed 🤷‍♂️

I can move it there if this is the wrong place for it

this is on immersive engineering, why post this here

it's not a rendering thing
