Description
Adding a DropShadow to a QtQuick scene breaks all mouse input. The following simple example demonstrates the issue:
import QtQuick 2.12 import QtQuick.Window 2.12 import QtGraphicalEffects 1.0 Window { visible: true width: 640 height: 480 title: qsTr("Hello World") Text { anchors.centerIn: parent text: "Hello, WASM!" } Rectangle { id: rectangle width: 100 height: 100 color: "red" visible: false enabled: true } MouseArea { anchors.fill: rectangle drag.target: rectangle } DropShadow { anchors.fill: rectangle source: rectangle verticalOffset: 4 horizontalOffset: 4 radius: 10 } }
The red rectangle is draggable on other platforms, but not in the browser with WebAssembly.
This issue is likely related to QTBUG-74754.
A minimal example project is attached.
