To be clear, which is faulty, the Geany entry or KCharSelect?
KCharSelect and Clibpoard are fail less.
Is it possible for you to try a newer version?
I tried `geany 1.38 (built on 2021-11-05 with GTK 3.24.20, GLib 2.62.6)` from https://ftp.lysator.liu.se/pub/opensuse/repositories/GNOME:/Apps/openSUSE_Le... repository but result is the same.
I thought someone was building Geany on the Suse Open Build Service but maybe they stopped.
Yes, geany 1.34.1 is newest available from OpenSUSE repository.
