If, after a Bomber you apply a Rotate component, you may get some strange lines....

Here you can see the result of the Bomber.

It is perfect. No separation among the particles.

But if I connect the Bomber with a Rotate, I get something weird.

Those white lines should not be there.

Some thing here. The result passed through a Rotate but not rotated of any degree.

The funny thing is that, if I rotate of more or less than 45 degree, there is nothing.
Like here, 44 degree rotation.

I have found 45 degree angle rotates (or multiples of...) often expose subtle problems with floating point math. The round off error when using rotates this way creates this issues sometimes. Often ran into this in my tiling filters and had to size the quadrant to be slightly larger (like scaling 1.00001) before flipping the quadrant twice for symmetry. To fix this I would scale a quadrant up just a little, then flip it twice to remove the "holes".
Math meets art meets psychedelia.

Yes. rachelduim is right.

I think it should be solved, because for some filter it is important to have exactly 45 degree or multiples of it.
