1. Using birch branch, go to http://people.mozilla.com/~nhirata/html_tp/formsninput.html
2. type in characters using nicoWnnG IME
3. before committing delete the characters

Expected: no flicker
Actual: chance at flickering.

Note: 
1. on main birch build : 10272011, type in a kanji character commit it and then type some uncommitted characters and delete the uncommitted characters
2. on Alex's build (see bug 640025) you don't necessarily have to commit a kanji character; it has a smaller chance of flickering with this IME.

Naoki, what flickering do you mean? For the whole screen or just for the text?
It's not quite clear from that up-side-down video.
you can see the flicker between 3 and 4 seconds into the video, 11 and 12 seconds, 15 and 16 seconds, 23 and 24 seconds.  The whole screen flickers from left to right.  Sorry for the upside down, I'll try to shoot another one if it's still not clear.

Yes, I noticed that, just wasn't sure, because it's not really about the input.
Very interesting - this happens only when entering text with that IME?
It only occurs when deleting uncommitted input.

Unlike other IMEs nicoWnnG causes an extra view resize when it shows, hides or changes the suggestion box. We redraw the surface on resize, that's what causes flickering. Sometimes just the area where the suggestion box was redraws, less frequently it's visible for the whole window. I'm not sure if we can do anything about this.

flickering still occurs with tinderbox build.
