Priority: P1: Critical
Affects Version/s: 5.12.4
Fix Version/s: 5.12.5
Component/s: Quick: Widget
Environment:OS: Windows 10 x64
Compilers: MinGW (32 and 64), MSVC (32 64)
Installation: Online Installer
When closing an widget containing a QQuickWidget and opening it again the scene becomes black.
This is a major regression since this does not happen with Qt 5.12.3.
See attached example application.
The following steps are used to reproduce:
- Build and run the example with Qt 5.12.4
- Push the button to open the Widget
- Close the Widget that opened by pressing the "x" button
- Press the button again to re-open the widget.
Expected behaviour: The widget should re-open with the list shown on the widget.
Actual behaviour: The widget is displayed with a black scene. See attached screenshot.
Repeat the above steps but this time using Qt 5.12.3. The widget is shown with the correct information after re-opening.
