Bug#900252: Gnome hangs when switching keyboard layout

[Lumin]

Package: gnome-shell
Version: 3.28.2-1
Severity: important

I have two keyboard layouts, English (US) and German (DE), which are
configured via gnome control center -> region and language -> input
sources.

When switching the keyboard layout between English and German,
the gnome shell will hang at a small probability. I don't know
how to manually trigger that, but it happens occasionally.

This problem should be set to imporant because it may be annoying for
multi-lingual users.
