Bug#931280: gnome-shell: Keyboard layout randomly alternates

Package: gnome-shell
Version: 3.30.2-9
Severity: serious

Dear Debian folks,

With Debian Sid/unstable with the default GNOME session, that means 
Wayland is used, and with two keyboard layouts configured (Neo 
(default), and German) sometimes the keyboard layout changes from Neo to 
normal German without me pressing the corresponding shortcut. The 
notification in the GNOME Shell’s top bar also still shows de₁, which is 
for Deutsch (Neo 2), so it is not changed.

Unfortunnately I have not figured out, what causes this. My suspicion is 
that “X.Org applications” like Mozilla Firefox and Thunderbird are 
involved. Maybe the GDM session running in parallel has something to do 
with it? No idea.

Debugging help is much appreciated.

Kind regards,


PS: I chose the severity *serious*, because suddenly having a different 
keyboard layout can cause data loss, when you suddenly press key which
for example confirms the deletion of data, despite you thinking you
press a different key to abort on the keyboard you currently use.
