    Default KWin crashes

    KWin version: 4.8.4-2.3.1
    Every time the computer boots and I log in, I get a message from KCrash that KWin crashed. I click on OK and everything seems to be working fine (all desktop effects are working). If I log out and log in, I get the same message and behavior. If I run
    Code:
    kwin --replace
    in the 'Alt-F2' textbox, all goes well, and if I log out and log in again, there is no crash message about KWin.
    Also note
    Code:
    billy@desk-SuSE:~> kwin --replace
    QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
    OpenGL vendor string:                   ATI Technologies Inc.
    OpenGL renderer string:                 ATI Radeon HD 5800 Series 
    OpenGL version string:                  1.4 (2.1 (4.2.11762 Compatibility Profile Context))
    Driver:                                 Catalyst
    Driver version:                         2.1

    Linux kernel version:                   3.4.6
    Direct rendering:                       no
    Requires strict binding:                yes
    GLSL shaders:                           no
    Texture NPOT support:                   yes
    kwin(19123): glCheckFramebufferStatus failed:  "GL_NO_ERROR" 
    kwin(19123): Failed to compile fragment program:  
    kwin(19123): Shaders are not supported 
    kwin(19123): Shaders are not supported 
    kwin(19123) KWin::checkGLError: GL error ( PostPaint ):  "GL_INVALID_ENUM"
    Any idea why KWin crashes ? I see the 'Shaders are not supported' message, but I don't know what to do about it. I have the proprietary drivers, version 12.8.
    Thank you in advance

    No clues anyone ?
    I have also experienced this following behavior too. I log in and the effects sometimes do not work and Configure Desktop > Enable Desktop Effects > Enable desktop effects at startup is disabled (it normally should be enabled). If I enable this option and click apply, I get a message saying 'The following effects could not be enabled' and it lists all the effects I use. However, on the next boot, effects work. I don't know what causes the option to become disabled.

    What seems more important to me is this one:
    Code:
    Direct rendering:                       no
    no error messages during install of the Catalist driver?
    ° Appreciate my reply? Click the star and let me know why.

    I'm 99% sure there weren't any. Should I try uninstalling them and installing them again ?
    I have no idea how to uninstall them though, never had to do that...
