This issue was fixed in https://gitlab.gnome.org/GNOME/gnome-control-
center/-/merge_requests/994 which avoids changing `xkb-options` unless
the Alternate Characters dialog is opened. (That was originally part of
MR 910, but was split off so it could be merged without being blocked on
design
I have the same sort of issue... Ubuntu 20.04 (Ubuntu Studio spin).
