I can confirm that it does not seem to happen on Linux. I testet it on my old laptop, which is windows/linux dualboot. On Windows it crashes, with the same crash file as in my first report. On Linux it does not crash.

It appears to be related to the MeshSequenceCache modifiers on the flag objects. When I remove those modifiers, the crash no longer occurs.

I retested this on the latest daily build and the sphere is now invisible. It does obscure other overlays, so something is being rendered.
