+** fcitx input methods don't work with xwidgets.
+
+fcitx-based input methods might not work when xwidgets are displayed,
+such as inside an xwidget-webkit buffer.  This manifests as the pre-edit
+window of the input method disappearing, and the Emacs frame losing
+input focus as soon as you try to type anything.  You can work around
+this problem by switching to IBus, or by using a native Emacs input
+method and disabling XIM altogether.  For example, you can add the
+following line:
+
+    Emacs.useXIM: false
+
+In your ~/.Xresources file, then run
+
+    $ xrdb
+
+And restart Emacs.
