    Description

      Building and running the attached scene3d.zip (based on qt3d/examples/qt3d/scene3d) the memory usage gradually increases.

       

      The main source of memory leaks are instances of QShaderResourceBindings.

      It is created by the Renderer::updateMaterialDynamicData function and is not freed.
