My issue seems unrelated to this:
Kubuntu fresh install worked like a charm for 5-6 sessions. Virtual keyboard (settings->input) was disabled from the start. Yesterday I started the system, I saw iBus being enabled on the bottom panel but I didn’t enable it…
It came with this message
IBus should be called from the desktop session in Wayland. For KDE, you can launch 'systemsettings5' utility and go to "Input Devices" -> "Virtual Keyboard" section and select "IBus Wayland" icon and click "Apply" button to configure IBus in Wayland. For other desktop sessions, you can copy the 'Exec=' line in org.freedesktop.IBus.Panel.Wayland.Gtk3.desktop file to a configuration file of the session. Please refer each document about the "Wayland input method" configuration. Before you configure the "Wayland input method", you should make sure that QT_IM_MODULE and GTK_IM_MODULE environment variables are unset in the desktop session.
I have wobbly windows and desktop cube activated. Apart of that - no major changes to the system settings.
Then the windows started crashing. First one window becomes unresponsible and you cannot do move it or close it. Then, the remaining wndows become unresponsive but must still works.
This morning I installed THOS PACKAGES (some from GNOME because I run Evolution Groupware on KDE)
