Kernel panic in maccel_events during fast mouse movements (CS2)

[SpasaevDonut]

Describe the bug

Moving the mouse wide while the maccel is loaded causes a kernel panic after some time. The system completely freezes and requires a hard reboot.

This sometimes happens while playing Counter-Strike 2, specifically on "Surf" maps where fast, sweeping mouse movements are required. Haven't seen that in regular game.

Environment

OS: Arch Linux x86_64 / Wayland (Niri)
Kernel: 7.0.3-zen1-2-zen (also experienced the exact same panic on 6.x liquorix kernels)
Hardware: Lenovo Laptop (83JG/LNVNB161216)
Mouse Polling Rate: 250 or 500Hz(not sure)
Installation method: makepkg from this repo

My maccel config

Steps to reproduce

1. Install and load the maccel module.
2. Disable system mouse acceleration (set libinput accel-profile to flat).
3. Make wide mouse movement (e.g. playing a CS2 Surf map).
4. The display is being filled with square green artifacts and crashes into a Kernel Panic.

[cosmickitteh]

same issue occurs for me, only without fast mouse movements i think.
wasnt able to cause the same error on the desktop/without a game open.
