OTF projection affects 2.5d renderer

[qgib]

Author Name: Tom Chadwin (@tomchadwin)
Original Redmine Issue: 14381
Affected QGIS version: 3.6.0
Redmine category:symbology

---

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.

Issue still present in 3.6. Updated screenshots attached. 2.5D renderer, default settings (except angle changed to 90deg).

Still valid on both QGIS 3.16.15 and 3.22.2. It of course depends on the CRS being used. Since the CRS's of the layer and the project are different, shouldn't this be normal behaviour?
