Repro (works when a version less than 7.10 is chosen)
After this PR edges are missing when culling is turned on using engine.setState with onBindObservable. Could be user error but reporting here just in case.
Reverting this line fixes it:
This is a user error. The material used to render the edges is created with backFaceCulling = false, so if you enable backface culling, it will fail. As a general rule, you should never call engine.setState yourself; the system will do this based on the settings you have defined for your material.
