Good advice Luisillo... I did review my viewer settings.  For 
Firestorm 4.7.1, I do have camera constraints disabled, and I have 
the default setting for  Firestorm -> Extras -> "enable progressive 
draw distance stepping" which is unticked.

You see 1024x1024 as that is the region size you are on.  Normal 
region users I think see just 256m which can be shorter than the 
viewer set max draw distance, and the terrain that shows is from the 
AVATAR position, not where the camera/viewer is placed as it should be.

The problem seems to be the commits db5a42 (2014-03-17) and 22dade 
(2014-03-21) by Robert Adams which changed the algorithm to use 
distance from avatar for terrain loading.  And commit c26f01 
(2014-02-19) also by Robert which did a temp fix that may still be in use?

This can be corrected (for non-varregion users) if OpenSim.ini [Terrain] has
SendTerrainUpdatesByViewDistance=false

I have added notes on this at http://opensimulator.org/mantis/view.php?id=7592

and I have suggested to Robert that the default might be better set 
to false until the code works properly from the viewer distance 
rather than distance from avatar.
