When sprinting, riding a boat, swimming, or flying, the debug screen shows chunk updates between 0 and 10. As soon as I stop moving the chunk updates will spike up to 70 and as high as 100. When riding a boat, swimming, or flying, it is easily possible to move off the rendered world into unrendered space with entities visible. Once I stop moving in the unrendered space, the world begins rendering out. This makes it impossible to move any faster than walking. This. seems to be new with 1.14. Never experienced this before.
