Bug report #14381

OTF projection affects 2.5d renderer

Description

Symbolizing a layer with the 2.5d defaults works if the view projection matches the layer. If another projection is chosen (OTF), the rendering fails, relating to rendering order:

- objects further from the camera overlap nearer objects
- further elements of a feature's geometry overlap nearer elements

I have no idea how general this issue is, or whether there is something specific to my data or choice of projections.
