- RTA findings here
- Supported development platforms are listed here
All platforms
Qt Quick 3D
v6.3.1 - Global scaling is not applied on asset import (QTBUG-104118).
Linux
Qt applications using QProcess crash when run in qemu (QTBUG-98951) or under valgrind (QTBUG-87230).

-no-feature-forkfd_pidfd
macOS
Windows
It's impossible to run Qt tests when building Qt from sources with a custom CMAKE_PREFIX_PATH containing Windows format paths with backslashes.
- Workaround: Use paths in CMake format to specify CMAKE_PREFIX_PATH when building Qt.

iOS
v6.3.1 - Building qmake projects will fail trying to link to hardcoded CI paths (QTBUG-104396)
WebAssembly
v6.3.1 - Building qmake projects will fail trying to link to hardcoded CI paths (QTBUG-104396)
Qt applications which use time zone or calendar functionality may fail to link, with errors like "error: undefined symbol: _get_daylight" (QTBUG-101267). Workaround: build Qt from source using a more recent emsdk version, for example 3.1.6.
Static Qt
