A fix for this issue is + scheduled for Qt 4.5.1. We recommend that developers who rely on this + compiler wait until the fix is applied before upgrading to the Qt 4.5.x + series of releases. + + \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 4.5, 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 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. + \endlist + + \section2 Windows Software Issues + + \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 + --- a/mkspecs/features/win32/embed_manifest_exe.prf + +++ b/mkspecs/features/win32/embed_manifest_exe.prf + @@ -8,4 +8,9 @@ if(win32-msvc2005|win32-msvc2008):!equals(TEMPLATE_PREFIX, "vc"):equals(TEMPLATE + QMAKE_POST_LINK = $$quote(mt.exe -nologo -manifest \"$$replace(OBJECTS_DIR,/,\\)\\$${NOPATH_TARGET}.intermediate.ma + nifest\" -outputresource:$(DESTDIR_TARGET);1$$escape_expand(\n\t)) + QMAKE_POST_LINK += $$QMAKE_PREV_POST_LINK + QMAKE_CLEAN += \"$$replace(OBJECTS_DIR,/,\\)\\$${NOPATH_TARGET}.intermediate.manifest\" + + isEmpty(RC_FILE) { + + system("echo.>$$replace(OUT_PWD,/,\\)\\$$replace(OBJECTS_DIR,/,\\)\\Windows7WorkAround.rc") + + RC_FILE = $$replace(OUT_PWD,/,\\)\\$$replace(OBJECTS_DIR,/,\\)\\Windows7WorkAround.rc + + } + + + } + \endcode + + \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.
