Pen starts to have long delays after some usage, dmesg says wacom_idleprox_timeout: tool appears to be hung in-prox. forcing it out.

Device: Thinkpad X1 Yoga 6th gen
Stylus: Lazarite AES pen, builtin pen (same behavior)
OS/kernel: Gentoo, Linux 6.6.13

Normally the pen delay is relatively small (although still slower than on Windows), but after a while of usage it becomes much slower (cursor lagging behind). When this behavior occurs, each approach of the pen is accompanied by this message in dmesg:

wacom_idleprox_timeout: tool appears to be hung in-prox. forcing it out.

Reboot fixes it temporarily

The same problem is still present in kernel 6.13.6.

By the way, is there a way to forcibly reset the state of the driver? It seems that rmmod -f wacom is not enough, and the pen appears to work even without the module loaded, which is odd.

I have the same problem with a Lenovo Yoga 7 2-in-1 14AHP9 (also AES pen with Arch Linux).
I did not find a solution other than restarting the laptop. The behavior seems to get better when enabling full preemptive in the kernel parameters, but it still exists.
