Comment(by hamish):

 see also #2175, since it is also seen from the command line with
 m.nviz.image, the root cause seems to be in the ogsf library functions.

 what happens is the transparent planar surface is rendered first, then the
 DEM is rendered over the top of it, instead of the DEM being rendered
 first then the the transparent planar surface rendered through it.

 Similar behaviour is also seen for #2175 in devbr6, and perhaps 6.4 too
 (untested).
