Description
After updating my app to Qt 6.5.1 I've started notice some strange warnings in the output
qrc:/qt-project.org/imports/Qt5Compat/GraphicalEffects/GaussianBlur.qml:288:5: QML ShaderEffect: Cannot find member data
This happens on app closing when QML scene is destroying

As far as I remember there was no such problem with Qt 6.3.2, so it looks like a regression.
Curious that no GaussianBlur is used directly in the app, but there are other effects like DropShadow.
