System Information
Operating system: Linux-6.0.9-arch1-1-x86_64-with-glibc2.36 64 Bits
Graphics card: NVIDIA GeForce RTX 2060 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 520.56.06
Desktop manager: dwm-4.2(https://dwm.suckless.org/) / Gnome (same behavior)

Blender Version
Broken: version: 3.3.1, branch: master, commit date: 2022-10-04 18:35, hash: b292cfe5a9
Worked: same copy but in Ubuntu 20.04

Short description of error
The bug showed up when first time opening blender in new OS.
With Continuous Grub option set on, mouse will jumps to a different position when release middle button or mouse exceed window border.
Bug exists in every possible editor, 3D, image, timeline, etc.

Exact steps for others to reproduce the error
Default cube, Middle Button/Shift+Middle Button/Ctrl+Middle Button to Rotate/Pan/Zoom.
Mouse will stay in release position but jump to a different position as soon as move mouse or press mouse button.
When mouse exceeds board of blender window, mouse will jump to a new position each mouse input.
Everything works fine when Continuous Grub set off.
Everything works fine with Ubuntu 20.04+Gnome

I'm not sure this is a Blender issue or an Linux issue.

I've confirmed this is not a bug with Blender, but with libinput and dwm.

Setting mouse speed through Coordinate Transformation Matrix

xinput --set-prop <device> "Coordinate Transformation Matrix" $speed, 0, 0, 0, $speed, 0, 0, 0, 1

will cause mouse jump to wrong position when software trying to set mouse position (Blender Continuous Grub, dwm resizing floating window, etc.).

To solve this issue,
set Coordinate Transformation Matrix to default value

xinput --set-prop <device> "Coordinate Transformation Matrix" 1, 0, 0, 0, 1, 0, 0, 0, 1

use libinput Accel Speed or Device Accel Constant Deceleration instead to adjust mouse speed

xinput --set-prop <device> "libinput Accel Speed" -1
# or
xinput --set-prop <device> "Device Accel Constant Deceleration" 2
