- QCache related crash on DNS lookups (QTBUG-89176)
- Any Qt Quick Controls 2 applications that still set the Default style will not start. The fix will be available with 6.0.1. The workaround is to set a valid style. (QTBUG-89286)
- There are known issues with CMake 4.18.2 and multi-config ninja that prevend building Qt with a -debug-and-release build. Please consider updating CMake in such cases.
- Minimum glibc version for prebuild binaries is 2.28, see https://bugreports.qt.io/browse/QTBUG-88833
- Workaround: compile Qt 6.0.0 by yourself or update glibc to 2.28 or newer
- Static builds with MSVC are not currently possible due to some filenames causing MAX_PATH to be exceeded (QTBUG-88581).
- Qt 6.0 for Android doesn't support multi-abi builds, it will be added in the next release (QTBUG-88841).
- When using CMake properties like QT_ANDROID_PACKAGE_SOURCE_DIR, qt_android_generate_deployment_settings(target_name) must be added after setting properties to make sure they are included in the deployment JSON file (QTBUG-88840).
- Using CMake to build user projects requires manual tweak. Please use qmake for now.
- Qt Creator cannot yet build iOS CMake projects (QTCREATORBUG-25058).
- Starting deployed iOS application from Qt Creator fails, see https://bugreports.qt.io/browse/QTBUG-89058
- If you click the installed icon on the device (located on the last screen) it starts Ok.
