If I click System Tools > Fcitx and click the keyboard, my computer will freeze until I kill lxpanel, and my wifi is showing twice, as shown in the following image. I will ask how to fix Fcitx in a separate question, but for this question: How do I fix lxpanel showing wifi twice?
This is a known bug that ultimately lies in the fact that the lxpanel-indicator-applet-plugin shipped with lxpanel is trying to do the job of all other indicators (read: system tray icons). It does create conflicts with more than just networking and may also be the cause of your issues with fcitx.
The solution: remove the plugin:
Open a terminal and run lxpanelctl config
Click on the "Panel Applets" tab.
In the "Currently loaded plugins," click on "Indicator applets."
Click the "Remove" button.
Click the "Close" button.
Log out/in.
In lieu of the logout, you may need to restart nm-applet, fcitx, and optionally add the "Volume Control" plugin. Potentially more depending on what indicators the plugin was trying to manage.
Note this works on LXDE, so is only applicable to Lubuntu ≤ 18.04. Also note that previous versions have had issues with multiple icons due to nm-applet being launched more than once, which is obviously not the same situation.
