Bug#874392: gnome-shell: wayland session crashes on touch input to mpv window

[Zoltán]

Package: gnome-shell
Version: 3.22.3-3
Severity: normal

Dear Maintainer,

If I use my touchscreen in an mpv window when under a wayland Gnome session, it
will often crash gnome-shell and immediately kick me back to the gdm login
screen.

The only relevant line in my logs seems to be in dmesg:

[33842.776039] traps: gnome-shell[4108] trap int3 ip:7f90ca26d921
sp:7ffe73db1d20 error:0 in libglib-2.0.so.0.5306.0[7f90ca21d000+111000]

Thanks,
Zoltán
