Crash Report

no crash.

Per discussions on Discord, there doesn't seem to be anything we can do about this. The user reported the bug exists in Minecraft 1.21.3 without Sodium, so it is an upstream bug.

I swear it happens, idk what's the cause of it, but I have a video, it's more easy to notice it in person.
My device is ARM, but CPU and GPU acceleration are working, OpenGL 4.6 with freedreno drivers and Ubuntu 24.04.
As I have a peculiar setup, I don't think it's worth to make a bug report to Mojang, as it also happens on Vanilla game.
I shouldn't have bothered sodium devs 😅

As soon as the F3 screen shows, the FPS raises from 20 ~ 30 to 60

Maybe that's some kind of driver performance optimization that only applies when F3 is opened. I've seen this situation on some forums several times before, but haven't had the opportunity to investigate it.
