Steps to reproduce:
1. Add a lot of Tiledbackground with physics behavior.
2. Set Immovable to Yes.
3. Check Tiledbackground collision in event.
4. Run Debug Layout.
We can see "Moved cell/sec" very high (Moved cell/sec = 480) because there aren't moving objects, but with sprite no problems (Moved cell/sec = 0).
I expect the same result of sprite, (moved cell lowest).
