- Have a Qt version's bin directory in PATH.
I can reproduce the issue with the official release of Qt 5.14.1 as well as my self-built Qt 5.15.2.
- Start Qt Creator with empty settings but load the QmlDesigner plugin, e.g.:
- Create a new Qt Quick Application project.
Use the wizard's defaults. I can reproduce the issue with projects using qmake as well as CMake.
Creator will automatically open the project's main.qml.
- Start the Design mode.
Three windows will pop up which use the Window item's title from main.qml but are empty otherwise:
This happens with Qt Creator built on Qt 6.2.0 as well as Qt 6.2.1. With the same revision of Qt Creator built on Qt 5.15.2, I don't see the issue.
