Summary: Keystrokes appear backwards under load

           Summary: Keystrokes appear backwards under load
           Product: Fedora
           Version: 12
          Platform: i686
        OS/Version: Linux
            Status: NEW
          Severity: medium
          Priority: low
         Component: ibus
        AssignedTo: phuang(a)redhat.com
        ReportedBy: emil.styrke(a)gmail.com
         QAContact: extras-qa(a)fedoraproject.org
                CC: phuang(a)redhat.com, fedora-i18n-bugs(a)redhat.com
   Estimated Hours: 0.0
    Classification: Fedora


Description of problem:
When the system is under high load (i.e. when the appearance of typed
characters lags behind the actual typing) the queued up characters appear in
reverse order when typing in (for example) kate.

Version-Release number of selected component (if applicable):
Installed Packages
ibus.i686                                             1.2.0.20091204-2.fc12

ibus-qt.i686                                          1.2.0.20091206-2.fc12
ibus-rawcode.i686                                     1.2.0.20090703-4.fc12
kdesdk.i686                                           4.3.4-1.fc12
How reproducible:
100%

Steps to Reproduce:
1. Open kate with a large file (3.5 MiB seems to be enough on my computer)
2. Bring up the search bar (ctrl+f) and select option "highlight all"
3. Start search with a character that occurs many times in the document to
trigger the highlighting. Continue typing fast enough that the typed text
doesn't show up immediately in the search field.

Actual results:
When the search is done, the text typed while kate is busy appears in reverse
order (i.e. hello comes out as "holle".)

Expected results:
Typed text comes out in the order typed.

Additional info:
I first noticed this when I enabled ibus as input methods (System ->
preferences -> input method -> enable input method feature, "Use IBus
(Recommended)"), which is why this is reported on the ibus package.
It is easily reproduced using kate for me (probably because of how its search
function is implemented), but this happens sometimes in other apps too when the
system is sluggish.

I tried this but kate is frozen even if I disable ibus.

Probably I think your text file is needed to reproduce the problem.

>  I tried this but kate is frozen even if I disable ibus. 
Yes, that's expected.  The difference would be that when kate finally
unfreezes, the typed text appears backwards when using ibus and correctly when
ibus is disabled.

Unfortunately, I no longer have access to that text file (but it happened with
several different large log files), nor to the computer exhibiting the problem.

If you could send the big file, please reopen the bug.
Currently I have no idea to reproduce your problem.
