Hi,

Got exactly the same issue, with mostly the same stack:
Lenovo ThinkPad X1 Yoga 3rd
Fedora Linux 40 (Workstation Edition)
Linux 6.9.8-200.fc40.x86_64 x86_64
Wayland
GNOME Shell 46.3.1

And I also noticed that the pen input does not work iff the app covers the top left corner of the screen (or is within 20-50 pixels from it), an as long as the corner is not covered everything works.

journalctl reports when pen is not working:

Jul 23 04:13:07 x1f kernel: wacom 0003:056A:5146.0003: wacom_idleprox_timeout: tool appears to be hung in-prox. forcing it out.

libinput list-devices:

i am not sure but this is probably gnome and wayland thing. i have dual boot with gnome 42 and it does work perfectly on that. we might open this issue on gnome vcs

@OlaszPL everything worked for me several updates back as well, but I can't exactly say when things broke and on what exact package update.

Is it possible to you to find what is latest working version?

I downgraded gnome-shell to 46.0-1 and libwacom to 2.10.0-1 but it didn't work.

Yeah i also tried that. It works on 44, but i am not sure about 45, will chek that.

I have everything working on Gnome 45.5 but that's not a clean test -- different hardware.

This issue was closed 2 weeks ago, so we just have to wait for a new mutter release.
It appears that this fix is included in mutter 47 that would probably be released with Gnome 47.
