Description:

After upgrade to Gnome 42 on Wayland when opening a window the mouse stops working inside the window after couple of seconds. The pointer can be moved but can't interact with the window (scroll, click, hover) or the window title bar. It can interact with the rest of the system (gnome bar at the top). It happens typically after 5-60s after opening the window. It happens in all kind of windows (Gnome settings, chrome, firefox, spotify, gnome Terminal). After closing the window and opening it again it works for a couple of seconds. It happens with Bluetooth mouse but also with built-in touchpad. It only affects wayland, running gnome with Xorg works fine. Systemd journal does not include any helpful information. libinput debug-events still shows the clicks but the window does not react to it anymore.

Steps to reproduce:

1. Open a window
2. Wait
3. Try to inside the window click -> does not work


Additional info:


In the screencast you see libinput detects the clicks but at some point the window stops responding to it:

I opened a ticket in upstream mutter but no response yet https://gitlab.gnome.org/GNOME/mutter/-/issues/2285. I have the bug already since a couple of months since gnome 42 was added to archlinux.
