It used to work but this is a new bug present in rev. 437.

Same for me, with rev 437 problems using ParticleField with Particle Material.
Last rev it was working perfect, now I have big rectangles and animation is 
very slow.

Seb, could you have a look at this ?

sure, no problem. But a few questions first :-)

What do you mean by not clearing? You mean they're not being culled off screen? 

Which type of camera are you using? (there's a problem with the scaling of 
particles
on frustum camera that i still lack the mathematical formulas to fix!)

The problem with the rectangles may be a "feature"... particles are now scaled
depending on how far they are from the camera, so things that used to be fixed 
to a
pixel can now change size. But a better description of the problem (with 
examples)
would be helpful. 

thanks!

I was using a Frustum camera but now it's working fine again.
The problem was that, when a particule was behind an object (and culled), it 
was not
cleared (it "froze" at its last position and was not updated).

ok so this is only on a frustum camera? I thought I fixed culling on
frustum... can you confirm this issue is fixed now?

cheers
Seb
