How severely does this bug affect you?: 

●●○○ — It's annoying but I can work around it.

Steps causing the bug to occur: 

I'm noticing some slight glitches when filtering an image with "Pixel Image" set to big pixels (size 0,2 f.e.) and feeding that to a make scaled layer.

This happens on my 13" screen 1280x800px and happens whatever I resize the composition window to.

However, this doesn't seem to happen with all the feeded image sizes (could have something to do with their ratios perhaps).

1 - Some glitches can appear on the edges of the pixels.

2 - When an extra layer is set in front of the pixellized image layer and if the new layer width matches the pixel sizes, there are some offsets.

3 - I was wondering if the edges of the big pixels are sharp or may be a little blurry. But this part could only live in my imagination.

-

I've attached some screenshots + 2 compositions and some sample images that cause the bug on my screen. Just drag and drop the sample images to the window composition.

Not sure if these are separate bugs or just one and the same.

Have you found a workaround?: 

No. I can only see it with big pixels though.

Other notes: 

How severely does this bug affect you ? Is between 2 and 3 points. Cannot really deal with it for that composition but still it doesn't prevent me to use Vuo for other stuff ;)

Looks like a problem with rounding in Pixellate Image. And it seems to depend on GPU (different rounding problems seen on 3 different GPUs).

2 - When an extra layer is set in front of the pixellized image layer and if the new layer width matches the pixel sizes, there are some offsets.
3 - I was wondering if the edges of the big pixels are sharp or may be a little blurry. But this part could only live in my imagination.

Those are both because the composition is scaling up the image after pixellating it. See attached composition, which scales up before pixellating and uses real-size layers instead of scaled layers.
