bopomofo symbols display problems with different input method used in terminal

[redfish-lee]

I've encounter a problem that when Chewing user phrase editor works fine at this exeucutution, maybe the bopomofo symbols couldn't display well at next execution. And there's no settings changed between these two executions.

I'm not sure the problem is caused by input methods. Because I've test to use the same input methods for consecutive executions for more than 10 times and the problem just happened in random.

My environment

• Ubuntu 14.04
• iBus chewing

I think build and make works fine, but anyway these are what I've used to build through:

• libchewing3 0.4.0-3
• cmake 3.2
• qt5-default, qttools5-dev-tools and libqt5webkit5-dev
• gcc 4.8.4

any comments is appreciated (:

What is your Qt version? (Help -> About Qt in chewing editor.)

I also use Ubuntu 14.04 and I've encounter the same problem as yours. I solved by : " QT_HARFBUZZ=old ./chewing-editor "

$ QT_HARFBUZZ=old ./chewing-editor works!

via

https://bugs.archlinux.org/task/38355 http://doc.qt.io/qt-5/configure-options.html

Qt5 includes both the old harfbuzz (harfbuzz.old) and the new harfbuzz. Configure with -qt-harfbuzz or -system-harfbuzz options.

However, -no-harfbuzz can be set at runtime by setting QT_HARFBUZZ environment variable to old and that's the solution @BarneyCw suggested.

Thanks a lot!
