Now hopefully someone has a workround.
When I extrude an object, like a rectangle, it goes weird, and all the
faces on the front face are individually obvious when I render. Also
when I split (ALT-X) to objects, it seems to change the colour of the
shape, and I cant restore it. I tried make sharp edges without success,
as it makes the edges obvious. SO what do I do?

Subject: Re: [IML] QUEST: I think I have a bug
What do you mean by "weird"?
Do you mean it has a faceted appearance? That's strange.
To be honest, an extruded rectangle (i.e. a shoe box) _should_ have
sharp edges. I don't quite understand the meaning of your question.
Perhaps this helps: it's my recipe for (usually) picture-perfect
sharp/soft edges.
- Make sure your object has the Phong Shading attribute active;
- In Pick Edges mode, Pick All, Functions/Make/Make Soft Edges;
- Click in empty space to pick no edges, then Pick/Edge Filter;
deactivate Select By Face Count, and activate Select By Face Angle;
- Functions/Make/Make Sharp Edges.
With most objects, this will give you a perfect set of sharp and soft
edges. (Also great for Quickdraw display)

Prehaps I worded it badly.
Say I extrude a box which is setup as 100 by 100 with 1 by 1 sections.
When I render it I can see the line which goes inbetween the two corners
of the box, ie the triangles which form the face. Its very annoying.

If the two faces render with different lighting, you should activate
Phong shading and properly set up hard and soft edges on your object.
This should remove any sharp transition.

Phong shading was always activated, but using soft edges seems to help.
I think it may be a memory related thing.
