Using LOD causes slower full-res rendering with OpenGL2 rendering backend

Open a large geometry file e.g. http://graphics.stanford.edu/data/3Dscanrep/xyzrgb/xyzrgb_statuette.ply.gz

Show as surface and interact.
On my machine, if LOD is disabled, then interactions are quite smooth. If LOD is enabled, when one stops interacting, the full-res render takes a long time. I suspect it's rebuilding internal datastructures when toggling between lod-geometry and full-res geometry.
