+ \title Known Issues in %VERSION%
+ \ingroup platform-specific
+ \brief A summary of known issues in Qt %VERSION% at the time of release.
+
+ This page documents known problems with the packaging and installation in
+ Qt %VERSION%, as well as issues with third party software that we have
+ not been able to work around. For a list of such issues in previous Qt
+ versions refer to this page in the respective documentation.
+
+ For a list list of known bugs in Qt %VERSION%, 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/Qt460BetaKnownIssues}
+ {Known Issues Wiki}.
+
+ \section1 Installation Issues
+
+ \section2 Building the Source Package on Windows 7
+
+ \list
+ \o When building Qt 4.5.0 with Windows 7, the build fails with an error
+ message regarding failing to embed manifest. This a known issue with
+ Windows 7, explained in the Windows 7 SDK Beta
+ \l{http://download.microsoft.com/download/8/8/0/8808A472-6450-4723-9C87-977069714B27/ReleaseNotes.Htm}
+ {release notes}. A workaround for this issue is to patch the
+ \bold{embed_manifest_exe.prf} file with the following:
+
+ \code
+ diff --git a/mkspecs/features/win32/embed_manifest_exe.prf b/mkspecs/features/win32/embed_manifest_exe.prf
+ index e1747f1..05f116e 100644

+ + }
+ +
+ }
+ \endcode
+
+ \section2 Installing the Source Package on Unix systems
+
+ \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.
+
+ 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.
+
+ 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.
+ \endlist
+
+ \section2 Windows
+
+ \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 drag and drop icons 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.
+
+ \o With NVIDIA GeForce 7950 GT (driver version 6.14.11.7824), a fullscreen
+ QGLWidget flickers when child widgets are shown/hidden. The workaround
+ for this is to use \l{QWidget::}{setGeometry()} with a width/height 1
+ pixel bigger than your geometry and call \l{QWidget::}{show()}.
+
+ \o A bug in the Firebird database can cause an application to crash when
+ \c{fbembed.dll} is unloaded. The bug is fixed in version 2.5.
+
+ \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).
