    \title Known Issues in 4.4.1
    \ingroup platform-notes

    An up-to-date list of known issues with Qt 4.4.1 can be found via the
    \l{Task Tracker} on the Trolltech website which provides additional information
    about known issues and tasks related to Qt.

    \section1 Issues with Third Party Software

    \section2 X11 Hardware Support

    \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 4.4,
       for example. The crash does not occur in newer versions of the drivers.
    \endlist

    \section2 Windows Hardware Support

    \list
    \o When using version 6.14.11.6921 of the NVIDIA drivers for the GeForce 6600 GT under
       Windows XP, Qt applications which use drag and drop will display reduced size pixmaps
       when run alongside applications that use OpenGL. This problem can be worked around by
       reducing the level of graphics acceleration provided by the driver, or by disabling
       hardware acceleration completely.
    \endlist

    \section2 Windows Software Issues

    \list
    \o In Qt 4.4.0, when there is an accessibility client running, Assistant will crash when the
    user creates a new tab page and Designer will crash when the user drags and drops certain
    widgets (\gui{Column View} or \gui{Table Widget}, for example). This problem occurs with
    any application that queries for an accessibility interface; for example, Microsoft Narrator
    or Notepad++ (versions prior to 4.8.5) trigger these problems.

    \o Under certain circumstances Visual Studio Integration v1.4.0 will not be able to install
    the integration for Visual Studio 2005 on Windows Vista. An error message states that .NET
    Framework v2.0 Service Pack 1 is not installed. This is due to a problem with the built-in
    installation of this on Windows Vista. This issue can be fixed by installing .NET Framework
    version 3.5.
    \endlist

    \section2 Mac OS X

    \list
    \o If a sheet is opened for a given window, clicking the title bar of that window will cause
       it to flash. This behavior has been reported to Apple (bug number 5827676).
    \endlist
