I understand that Darcy applied Philippe's patch, so I close the bug.  Please re-open if I am wrong.

According to http://lists.gnu.org/archive/html/texmacs-dev/2017-09/msg00000.html, in Qt5 this can be cured by disabling a call to process_queypress:

diff --git a/src/Plugins/Qt/QTMWidget.cpp b/src/Plugins/Qt/QTMWidget.cpp
index d14b514..ce3cce0 100644

+if (!is_nil (tmwid))
     the_gui->process_keypress (tm_widget(), r, texmacs_time());

This rather seems a workaround than a proper fix retaining all the desired functionality, but I have'nt investigated the problem at all.

Thank you for the report and sorry for comming to it after so long...

I've seen a similar problem reported on the user mailing list (see the thread originated by http://lists.texmacs.org/wws/arc/texmacs-users/2017-02/msg00014.html). The bug was related to using the static build downloaded from texmacs.org website. Is it also the case for the issue reported here?

OTOH the same thread indicates that standard dynamic builds work properly with ibus... Right now we are working to bring new dynamic builds for most linux distros in the near future, including Fedora. I guess this will solve the problem, so stay tuned.

I'm using Qt 4.8.7 and Texmacs 1.99.2 on a Fedora 23 machine

What is your Qt version? Recently, my TeXmacs built using Qt5 has this problem too. I use Fcitx to input Chinese.

I'm using ibus to input Japanese on my system. However in Texmacs the unfinished input disappears immediately before hitting enter/space to convert hiragana to kanji. However Texmacs seems to create a yellowish 'pre-edit' tag.

If I keep pressing e.g. "a" and hit enter while doing so I can enter a string of "あ" characters.

Please contact me if you should need any further information.
