Shaky mouse movements

[Yamakaky]

Describe the bug
When using mouse and keyboard, the camera is very shaky. I can reproduce it easily on the desktop. When doing circles with the mouse, I see a nice circle when the cursor is unlocked, but when locked it becomes very shaky. I can feel that the cursors are not evenly spaced. This is very noticeable in FPS view.

I have a G502. I tried 500 and 1000Hz with piper, same results.

Playing on windows or with a controller gives a smooth movement, so it seems to be mouse specific on linux.

Is this a known issue? What can I do?

Install gnome-tweak-tool and set acceleration to flat, or disable any mouse acceleration in your environment

I did that using both xorg config in https://wiki.archlinux.org/title/Mouse_acceleration#Disabling_mouse_acceleration + disabling mouse acceleration on windows

I also tried with two other mouses, same result.
