Hi,

Yeah sorry I don't have a nice repro to send.

I'm pretty sure I did test this at the time, and it didn't work.  But I'll try
again to make sure.

I don't remember the details precisely, but there general idea is:
 - part of the scene is rendered
 - then the z buffer is converted to a linear texture
 - downscaled with a shader to a new texture
 - the new texture is then converted back to a htile zbuffer(*)
 - and some more rendering is done at that lower resolution, in parts not
occluded
 - and then all is blended together for presenting

So the problem is that the (*)transition does need to convert the data and not
just clear the buffer.
