(Linux, AMD) Massive stuttering when walking around, flying, etc.
While playing with shaders, performance drops massively when I do other things than standing still and doing nothing.
I do not recall having this issue with NVIDIA gpu, and from my testing it seems that it isn't connected with wayland.
Performance is a lot better on Windows much to my surprise, cause from what I know Minecraft runs better on Linux for most people compared to Windows.
GPU: RX 6800 XT
Mesa version: 25.0.3
Kernel: Linux 6.14.0-4-cachyos

Try turning off the option "Use No Error Context" in the video setting, see if it helps.
I checked but it's greyed out and I'm unable to even turn it on
Try 1.21.4
1.21.5 is known to have performance problems, even without mods
I am away from home for a week but I'll let you know whether performance will improve on 1.21.4 when I'll get back
