Hi Saif,
One other thing you could try to understand your bug better is make your
objects semi-transparent. I had that problem myself with the difference of
two objects each being composed of an intersection of others.
To make things simple to explain, say you have A, B, C and D all simple
objects (i.e. planes).
Now make E as the intersection of A and B and make F as the intersection of
C and D.
The final object, called G is the difference of F less E.
Making that object G semi-transparent and semi-reflective, putting a sky
sphere that is a gradient (just to make any reflection or transparency
obvious) shows the border line of C and D inside G (if they intersect at all
with the final G object).
Now if you use a merge all spurious border lines disappear.
This clearly is a bug, although I did not take time to report it when I got
it, but that makes two of us now as I'm pretty sure your problem is the same
as mine.
So if the POV-Team or POV-admin is listening, please pass on to the
programmers team.
Cheers & regards to all,
Al.
