@Narasimha said in QPushButton->setMenu(QMenu) transparent removal not working: Important: Explain internal Qt painting behavior. To add to @Axel-Spoerl : I mean regarding this point, you could look it up yourself, if you care... Qt has a very nice and detailed documentation. Basically you demand a final and ready-to-use solution while refusing to do little work yourself. And you also did not mention if it worked with Qt 4.8 before. Edit: Also, your code compared to your expected output does not make any sense... You apply a background-color #333 to both of your widgets A and B while your expected result shows a light gray background color for the left widget (assuming widget A). That makes me doubt that you've really taken the time to seriously look into the code or the problem.

@JonB Thanks for the link! There's border-radius, which makes the plain "StyledPanel" style possible but the website only mentions a shadow for "PaletteRole". Does this mean that you can't achieve the "raised" or "sunken" styles purely using QSS?

I wonder if it's because of scorePopupRequested

You should take a look at examples by QT for Tumbler QML; https://doc.qt.io/qt-6/qml-qtquick-controls-tumbler.html Try this, or parts of this code, this works for me; import QtQuick import QtQuick.Controls Window { id: window width: 640 height: 480 visible: true title: qsTr("Mouse wheel action") Rectangle { color: "khaki" anchors.centerIn: parent width: frame.implicitWidth + 10 height: frame.implicitHeight + 10 Frame { id: frame anchors.centerIn: parent Row { id: row Tumbler { id: tumbler model: 5 width: 200; height: width focus: true; wheelEnabled: false delegate: Text { text: modelData font.pixelSize: 18 horizontalAlignment: Text.AlignHCenter verticalAlignment: Text.AlignVCenter opacity: 1.0 - Math.abs(Tumbler.displacement) / (tumbler.visibleItemCount / 2) required property var modelData required property int index } } WheelHandler { onWheel: (event) => { tumbler.currentIndex += event.angleDelta.y > 0 ? -1 : 1 } } } } } } p.s. My mouse is old and the scroll wheel is very intermittent, but I think the above should help.

Hello. I have same issue. Windows 11 and Qt6.11.1 MSVC22 I take data from udpserver, and my speed 800-900 Mbps on Task Manager. How could I fix it ? Also my sockets works on different threads.
