See the bug report here:

This bug happens when using "fcitx" input method
(or other input method I think), the "preeditString"
get disappear.

This happens for 1.99.5 with Qt5 on Linux (there's
no bug for the Qt4 pre-compiled binary). After some
bisecting, I find this bug exists in 2016-05-17, I can't
compile earlier versions to give a precise commit.
I think around that time, Qt5 support is being added,
so I presume this bug is related with Qt5.

The following patch "fix" this bug.  It was supposed to
process and show the "preeditString", now I disabled that.

I hope this bug get resolved soon, because it affects almost
all CJK users.
