Greetings, 

nothing official, I'm a poor lone some cowboy...

Two (or three) remaining issues only so far (AFAIK):

 1. Random locking of the rendering process (as a whole) with a black 
preview window (at start of the rendering)
    Might be correlated to X11 errors reported otherwise
    When on local display, moving the mouse over the preview usually 
unlock the issue.
    When on remote display, you're stuck.

    Would prevent animation batch rendering with preview (workaround: 
disable the preview window, what a shame), as it might stuck any frame.
(or not...)


 2. Isosurface & bounding box
    2.1 containment by a sphere with bounding box on gives a kind of 
nebulous coincident surface effect. (Smellenbergh, 16th August)

povray -Ibug.pov -H150 -W200 +MB1 +A0.01

//start scene
global_settings{max_trace_level 55}
camera {location  <0,0,-18> look_at <0,0,0> angle 55}

background {rgb <.8,0.7,0>}

light_source {<-30, 100, -30> color rgb 1.6}
// light_source {<-30, -100, -30> color rgb 1.6}

#declare f_sphere = function { internal(61) }
#declare f_rounded_box = function { internal(60) }
isosurface {
  function { f_rounded_box(x, y, z, 0.3, 0.8, 1, 0.8)  }
//  contained_by{box{<-0.85, -1.4,-0.25>,<0.85, 1.4, 0.85>}}
  contained_by{sphere{<0,0,0>,0.9} }
  pigment {rgb 1}
  scale <3,4,3>
  translate x*4
}
//end scene


    2.2 With multiple threads (does not happen with only 1 rendering 
thread, nor with bounding box off): i_internal.pov rendering provides a 
checkered two-tones pattern (matching thread-rendering-square) on 2D 
pictures when intersecting the containing box.

(Has been duplicated on MS-Windows too)
