When checking your SceneNode dumps I found something unusual:

Code:

       SceneNode (192)   (IsVisible == false)  WorldBounds: (-340282300000000000000000000000000000000 -340282300000000000000000000000000000000 -340282300000000000000000000000000000000)->(340282300000000000000000000000000000000 340282300000000000000000000000000000000 340282300000000000000000000000000000000) [Infinity x Infinity x Infinity]    LocalBounds: (340282300000000000000000000000000000000 340282300000000000000000000000000000000 340282300000000000000000000000000000000)->(-340282300000000000000000000000000000000 -340282300000000000000000000000000000000 -340282300000000000000000000000000000000) [-Infinity x -Infinity x -Infinity]  Flags: Unchanged

Those two SceneNodes have very big bounds. If such object becomes part of the scene, then this can destroy depth-resolution - puts camera's far plane to almost infinity and this means that almost all objects would have almost the same depth (distance) to the camera (depth is calculated as a fraction of the far plane distance - using 32 bit float value).

Can you try to set the size of that object to a normal object's size and then check if your problem is fixed.
