    \title Known Issues in 4.6.3
    \ingroup platform-specific
    \brief A summary of known issues in Qt 4.6.3 at the time of release.

    An up-to-date list of known issues with Qt 4.6.3 can be found via the
    \l{http://bugreports.qt.nokia.com/}{Qt Bug Tracker}.

    For a list list of known bugs in Qt 4.6.3, see the \l{Task Tracker}
    on the Qt website.

    An overview of known issues may also be found at:
    \l{http://qt.gitorious.org/qt/pages/QtKnownIssues}
    {Known Issues Wiki}.

    \section1 Installation Issues

    \section2 Installing the Source Package on Unix systems

    \list

    \o  If you download a Zip source package, you will need to convert
        Windows-style line endings (CR/LF) to Unix-style line-endings (LF) when
        you uncompress the package.  To do this, give the "-a" option when you
        run the "unzip' command.

    \o  If you fail to supply the "-a" option when unzipping the package, you
        will see the following error message when you attempt to execute the
        configure command:
        "bash: ./configure: /bin/sh^M: bad interpreter: No such file or directory"

    \endlist

    \section2 Installing on Mac OS X 10.6 "Snow Leopard"

    \list

    \o Performing a new install of the Qt 4.6 beta on Snow Leopard
       triggers a bug in the installer that causes the install to fail.
       Updating an existing Qt installation works fine.

    \o There are two workarounds, either disable spotlight for the target
       drive during the install, or do a custom install where you deselect
       documentation and examples. Run the installer again as a full
       install to get the documentation and examples installed.

    \endlist

    \section1 Issues with Third Party Software

    \section2 X11

    \list
    \o  There is a bug in the 169.xx NVIDIA drivers on certain GeForce 8 series
        cards that is triggered by the OpenGL paint engine when using QPainter
        on a QGLWidget to draw paths and polygons. Some other painting
        operations that end up in the path fallback are affected as well. The
        bug causes the whole X server to repeatedly hang for several seconds at
        a time.
    \o  There is an issue with NVIDIA's 9xxx driver series on X11 that causes a
        crash in cases where there are several \l{QGLContext}s and the extended
        composition modes are used (the composition modes between and including
        QPainter::CompositionMode_Multiply and
        QPainter::CompositionMode_Exclusion). This affects the composition mode
        demo in Qt 4.5, for example. The crash does not occur in newer versions
        of the drivers.
