Status changed to 'Confirmed' because the bug affects multiple users.

[El jinete sin cabeza (ejsc)]

The shock was brutal, all my applications were closed. And then GDM appears.

[Sebastien Bacher (seb128)]

The issue was fixed upstream in https://gitlab.freedesktop.org/xorg/xserver/commit/2e18eec6

note that it's only a problem in wayland session and there are only 11 reports on e.u.c
