Summary:	So I was playing around with the 24.02 test release and found that once you full screen the preview window, it only displays a white screen and even if you exit the full screen preview, the white screen persists.

Hit F11, I get this message in DebugView:

[2348] qrc:/qml/kdenliveclipmonitor.qml:612:29: QML Rectangle: The current style does not support customization of this control (property: "background" item: QQuickRectangle(0x2aaa0407a20, parent=0x0, geometry=0,0 0x0)). Please customize a non-native style (such as Basic, Fusion, Material, etc). For more information, see: https://doc.qt.io/qt-6/qtquickcontrols2-customize.html#customization-reference

SubTitle.qml and TrackHead.qml have the same issue/message.
