Qt 5.9.5 Known Issues

All platforms

• Check that your system meets Qt's requirements
• All open issues can be found from Jira: https://bugreports.qt.io
• Old qt-unified-online-installer-3.0.1 (or older) can't any more be used to get Qt 5.9.4 (or later releases), see QTBUG-65798
  • For new installations use newest online installer (qt-unified-x86-3.0.2-online). For existing installations please update maintenance tool at first.

Windows

• Static builds of Qt with Microsoft Visual Studio 2017 (through Update 2) do not work and will likely crash at runtime. This is believed to be a compiler bug and therefore an update from Microsoft is required. See https://bugreports.qt.io/browse/QTBUG-59721.

Linux

Building Qt modules fails with binaries delivered with online installer see bug QTBUG-53865. Workaround is to build whole Qt from source or have libicu 56 installed on the system.
