Character duplication when changing windows

I have the same problem. After keying in some Chinese characters (still in Chinese input mode), clicking the window title will cause the Chinese characters to duplicate. One click causes one duplication. Switching to another window and coming back also has the same problem. Such a problem is very annoying because my document has duplicated characters here and there without my awareness. Any ideas?

System spec.:
Ubuntu: 10.10
Ibus: 1.3.9-1phuang1~maverick1
Ibus-chewing: 1.3.7-20100910-1hychen1
Python-ibus: 1.3.9-1phuang1~maverick1
Python: 2.6.6-2ubuntu2
Python-gtk2: 2.21.0-0ubuntu1

Another syndrome:

In gedit, OpenOffice Writer, or a browser's text input column, after I mark some texts, if I toggle to Chinese input mode and toggle back, the marked texts will be deleted. This is also very annoying because some of the texts in my document are gone without my awareness.

This bug report has been here for more than a month. I wonder when will it be taken care of?

@perry can you give me what ibus version you used?

@yltang 1.3.7-2010901-1hychen1 is for ibus-1.3.7, I have not test it with ibus 1.3.9

@hychen I am using 1.3.7.20100910-1hychen1 since you have fixed all of the other problems and the official version has not (to my knowledge).

@hychen Sorry, let me be more specific. ibus-chewing 1.3.7.20100910-1hychen1 , ibus 1.3.7-1ubuntu4

I also use ibus-chewing 1.3.7.20100910-1hychen1 , ibus 1.3.7-1ubuntu4 but can not reproduce in my machine

 can you guys give me your ibus Preferences configuration?

Now I have upgraded to Ubuntu 11.04 and ibus-chewing 1.3.9-2.2, but the problem is still there :-( A more specific way to reproduce it: put the cursor in the Google search box of Firefox, type some Chinese characters, and then hit Enter so that they appear in the text box. Now, click the title bar of the window and you will see that the characters just entered is pasted twice. One click causes two pastes. Maybe it's because the characters in the buffer don't get cleared after hitting the Enter, and clicking the title bar causes them to be input again.

I hope this problem will be fixed soon because I like Ibus-chewing very much, and I really don't want to switch to other input methods.

Thanks for your time and effort.

reported bug to upstream http://code.google.com/p/ibus/issues/detail?id=1245

ibus-chewing does not clear commit String and status is still in NEED_COMMIT after User press Enter to complete all input behavior, so the commit string will shows in the box user focus-in after focus-out event appears/

There is another syndrome I forgot mentioning.

1. Run LibreOffice/OpenOffice Writer and Firefox. Adjust the two windows such that they are visible on the screen (we need to click on the window titles later).

2. In Writer, key in some English texts under English input mode, highlight/mark these texts, and then toggle to Chinese input mode by hitting Ctrl-Space

3. Now click on Firefox's title bar. --> Boom! The texts in Writer are gone!

In addition, in LibreOffice/OpenOffice Writer, type some English texts under the English input mode and then mark those texts. Now toggle to the Chinese input mode and toggle back to the English input mode by hitting Ctrl-Space twice. The marked texts will be deleted.

這個問題還沒有解決嗎？
看到之前輸入的片段字句一直出現真的非常的擾人...
Please fix it quickly...

Please try ibus-chewing 1.3.9.2-1hychen1 in https://launchpad.net/~ossug-hychen/+archive/ibus, it should fix the duplication problem.

in natty, firefox with ibus-chewing has a another issue after apply this patch which is you can not type any words after switch focus to another input filed after press Enter, I will continue to figure out root cause.

Tested hychen's ibus-chewing on oneiric, and confirmed his version fixed the state machine (character duplication) issue.

the bug also be tracked in libchewing bug tracker http://code.google.com/p/chewing/issues/detail?id=308

Sorry, but how do I install "ibus-chewing 1.3.9.2-1hychen1"? I have added "ppa:ossug-hychen/ibus" to my system's Software Sources. But the system didn't seem to upgrade.

@yltang what is your ibus-chewing version? you can type "dpkg -l|grep ibus-chewing" for finding the version

patch is merged in ibus-cheiwng upstream, please see (https://github.com/definite/ibus-chewing/commit/8630456806f220734b08d53d5e843e942bbd0aea)

dpkg -l|grep ibus-chewing

--> 1.3.9.2-2

The problem is fixed with hychen's ibus-chewing.

But the old problem -- the first tone char will disappear when typing it as first char -- is appear again. It affects me and some users on ubuntu-tw (http://www.ubuntu-tw.org/modules/newbb/viewtopic.php?post_id=198280#forumpost198280).

I am using Natty and the version of ibus and ibus-chewing is

ii ibus 1.3.9-0ubuntu3 New input method framework using dbus
ii ibus-chewing 1.3.9.2-1hychen1 chewing input engine for IBus

and this old problem is not existent if I downgrade the ibus-chewing back to 1.3.9.2-1.
