MATE completely freezes when I click on the fcitx applet

[Mattia]

Whenever I am in an active text field (when the language shows in the applet) and I click on the applet on the top right to change layout, MATE completely freezes (I can't click anything, but the clock keeps going). Only thing I can do is either restart lightdm or reboot. The workaround I use is using the keyboard shortcut to change layout. That does not freeze anything.
