Hello,

I've seen this several times now with different fractals, and I don't know what causes it, but sometimes multi-layer fractals are offset. This problem seems to go away when activating anti-aliasing in the working window. Here's a screenshot:

It seems to be always exactly 1 pixel along the y-axis of the monitor, no matter the rotation of the fractal. And it also remains 1 pixel while using shift + mous drag to zoom, here's an screenshot while doing that, you can see the offset at the border between the enlarged pixels:

Here's the fractal:
