User-Agent:       Mozilla/5.0 (X11; U; Linux i686; fi-FI; rv:1.9.2.6) Gecko/20100628 Ubuntu/10.04 (lucid) Firefox/3.6.6
Build Identifier: 

Moving cursor inside input box leaves traces when the mobile browser is in E10S mode.


Reproducible: Always

Steps to Reproduce:
1. Put browser in E10S mode by setting browser.tabs.remote to true.
2. Open a page with input box, for example http://www.google.com/
3. Place focus to input box (and wait until the box is zoomed)
4. Type text "fdklfjkgfhgölöltrtrgfddsmbgf" or something similar.
   The main thing is that the width of the letters varies.
5. Move cursor from beginning to end and back a few times..

Actual Results:  
Cursor movement leaves traces.

Expected Results:  
Cursor shape is cleared completely from previous place when cursor moves
forward/backward.

Happens with GTK+ and Qt desktop versions. Tested on Ubuntu Linux 10.04/i386 with Qt 4.6 and GTK+ 2.20.
