just registered and already with my first question.
I installed fcitx via Synaptic, including its dependencies. Then I noticed, the icon for selecting the keyboard input and its menu look out of place, see the following screenshot:
I thought it had to do with a package that got pulled as recommend and I suspected it to be kde-config-fcitx, so I removed that and rebootet. And then the "normal" icon and KDE native menu appeared.
However, upon rebooting again, it is all back to how it was before. I reinstalled kde-config-fcitx but it didn't change anything.
