[Users] CM errors on startup and menubar

[Ilja Rogoff]

Hi folks,
since a few days I am experiencing some errors when starting claws and
when working with it:

Starting from console I get the following messages:

The effect in claws is, that when I click on the menubar, e.g. at
"Configuration", the menu bar opens at "File". And often after that,
claws freezes.

My guess is, it has to do with latest KDE6 Plasma updates?
My system: openSUSE Tumbleweed, KDE6.3, wayland

When switching to Plasma (X11), claws works as it should, but I also
have some errors on startup:

> claws-mail:41748): Gtk-CRITICAL **: 17:07:07.865:
> gtk_style_set_background: assertion 'window != NULL' failed

> (claws-mail:41748): Gdk-CRITICAL **: 17:07:07.865:

Anyone else having these? Or may you give me a hint to solve the issue?
