How to get uniform zoom tiles in the current view during the loading?

Sometimes with a slow Internet connection I get a situation where higher zoom tiles are rendered next to the low zoom tiles, and it looks patchy like in the picture below:

After few moments all the loading is done and the terrain looks nice and uniform:

My question is, what can I do to not to render the higher level tiles in the camera frustum until all of them are completely loaded?

Hello,

Sorry, but that kind of functionality is not currently part of Cesium. We would like to improve tile loading in the future, but right now we’re really focusing on implementing the new 3D tiles specification.

Best,
