           Summary: Kwin causing xorg crash after applications are reduced
                    in taskbar
           Product: kwin
           Version: unspecified
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: compositing
        AssignedTo: kwin@kde.org
        ReportedBy: eric.lemoussu@gmail.com


Version:           unspecified (using KDE 4.4.4) 
OS:                Linux

After xorg 1.8 update I have a systematic problem of crash/restart of xorg when
deducing then reopening applications.

No information found in logs (as far as I know).

Not much info apart from that, except I'm on latest KDE with composition
activated and I'm using opensource Radeon driver.


Reproducible: Always

Steps to Reproduce:
With:
- Open source radeon driver (my card in an X300, rv370)
- KMS disabled
- Desktop effects enabled

1- Open any application.
2- Reduce opened application in taskbar
3- Show app again (clik in taskbar or alt-tab, same thing)


Actual Results:  
X crashes and restart on KDM login

Expected Results:  
Reduced window should repoen

I fisrt though of an xorg bug because of recent 1.8 update. But problem is
solved when desktop effects are disabled, so there must be a KDE issue there.
Bug does not occur with KMS enabled (not a solution for me as enabling KMS
really slows my machine after a while).

Computer config:
Dell Inspiron 6000.
Intel Celeron
ATI X300 (open source radeon driver)
Archlinux vanilla KDE
