QML/VTK : QQuickRenderWindow with ui elements on top of that create undesired rendering call
With vtk 9.1 or newer and QML based on QT 6 (tested with QT 6.2.1), we have some limitation when UI elements are superimposed on the vtk render window. When user moves his cursor on theses UI elements, a vtk rendring was call.
It seems to be related to a current limitation in QQuickVTKRenderWindow
