I am running Qt3D in Qt 6.0.0 using the RHI renderer.

My use case is drawing of a continuous line and then animating it by setting the vertice count. The line is created with a vertex buffer, per vertex color buffer, and index buffer. To perform the animation I am repeatedly calling setVertexCount in the geometry renderer.

m_geometryRenderer->setVertexCount(count);

Unfortunately, doing this causes an increasing memory consumption, at least as shown in Visual Studio. Running the same code, but with this line commented out, resolves the memory increase. This causes me to believe that there may be a leak associated with this.
