Summary: Switching on/off behaves weird when compositing enabled

https://bugzilla.redhat.com/show_bug.cgi?id=500731

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: [e-mail]
        ReportedBy: [e-mail]
         QAContact: [e-mail]
                CC: [e-mail], [e-mail]
   Estimated Hours: 0.0
    Classification: Fedora

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

Please try ibus with compiz. I can not reproduce this problem with compiz. I
think it is bug in metacity.

I'm afraid I cannot do that. Just tried enabling compiz via
System->Preferences->Look and Feel->Desktop Effects and it told me that it
cannot be enabled... So I cannot confirm this test case :(

To answer a question asked in the other bug:

metacity and compiz are different implementations, thus their behaviour differs
in handling certain corner cases. I'd say that ibus probably does  not pick the
best window type for this toolbar, or doesn't do the right thing to make it
disappear.

Created an attachment (id=351707)
 --> (https://bugzilla.redhat.com/attachment.cgi?id=351707)
test case for reproducing this bug

I created a test case in python for reproducing this bug. In this test case, it
just calls gtk_window_set_opacity after gtk_widget_hide_all. I think metacity
should handle this case correctly.

Quick testing here with metacity-2.26.0-1.fc11.i586:
* as it is the window stays visible after clicking hide
* when removed set_opacity in the init, the window initially hides after
clicking hide, but reappears after switching between other windows
* when removed set_opacity in the hide func. it behaves as expected (i.e. the
window hides forever)

--- Comment #10 from Bug Zapper  2010-04-27 10:19:16 EDT ---

This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '11'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 11's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 11 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
