Bug report #20691
3D without elevation layer renders badly

If I don't have an elevation layer to generate the terrain QGIS should apply a flat terrain model so I can render 3D objects from vector layers.
It does render, but pan, zoom and orbit is "jumpy" and unpredictable. Even the simplest models renders poorly (attached file).
As soon as a terrain layer is applied as elevation source, all issues are resolved.
