Hi, When I try to open .ui.qml files in QtCreator panels not appear properly, they get black & does not work. Does any one knows to correct this problem. Following is the output on console when I open a file (I removed repeating lines because this get too long): void QWindow::setTransientParent(QWindow*) QWidgetWindow(0x36773e0, name = "QmlDesigner::Internal::DesignModeWidgetClassWindow") must be a top level window. libpng warning: iCCP: known incorrect sRGB profile QQuickWidget cannot be used as a native child widget.
