           Summary: Switching on/off behaves weird when compositing
                    enabled
           Product: Fedora
           Version: rawhide
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: medium
          Priority: low
         Component: ibus
        AssignedTo: phuang at redhat.com

Description of problem:
Turning ibus on or off does frequently makes the tool window either
semitransparently reapear after switching to another window (and is not
clickable/working) or not appear (save for its shadow and it is
clickable/working). I can seem to trigger this only when I have compositing in
metacity enabled. Tried chewing and anthy inputs, both suffer from this.

Version-Release number of selected component (if applicable):
ibus-1.1.0.20090508-1.fc11.i586

How reproducible:
seems to be always reproducible sans some applications (e.g. when switching to
ibus settings window, it seems to behave correctly)

Steps to Reproduce:
1. turn on metacity compositing
(gconf->apps->metacity->general->compositin_manager)
2. open two gtk applications that take input from keyboard (e.g. two
gnome-terminals)
3. switch to and fro between those two applications while randomly turning ibus
on and off

Actual results:
Usually after turning it off and switching to other window, the toolbox
reappear (but is semitransparent and not clickable/working), switching back,
turning on and off again and switching again to the other window seems to work
as expeced. Switch back to the first window and turn it on again, usually blank
(fully transparent) toolbox appears. Turning off and on again fix it (or
switching again to and fro between the two applications without explicitly
turning it on/off).

Expected results:
Turns on and off without the strange side effects.

Additional info:
It seems impossible to make a screenshot of the not-appearing one, hitting
print screen makes it reappear. Screenshot of the "false positive" is at
