Hi,

I'm a bit new to POV so maybe I'm asking an obvious question. I stumbled across
this problem that I can't figure out.

I have this scene:

#include "colors.inc"

global_settings { assumed_gamma .5 }

camera {
    location <0, 4, -6>
    look_at  <0, 0,  0>
}


plane {
    < 0, 1, 0 >, 0
    pigment {
     checker
     color Red, color Blue
    }
}


light_source { <5, 3, -40>, color White}

which produces this image: <test1.png>

Then I change the orientation of the plane from <0,1,0> to <0.2,1,0> and this
is the result: <test2.png>

If I change the orientation even further to <1,1,0> it gets even worse:
<test3.png>

I'm using WIndows XP (Home) with POV-Ray 3.6.0.icl8.win32

Can anyone explain what causes the shrinking/disappearance of (some of) the
tile rows and how to overcome this?
