Also think this is ok.  
you expect something that would be done by:

- using different z coordinates (between bottom and top vertices)
- and/or maybe transforming the stack  
Not sure, but maybe there was this patch would be helpfull … [https://github.com/libsdl-org/SDL/issues/1229](https://github.com/libsdl-org/SDL/issues/1229)
