"Mask to path" seems not working at all on non-square images

Excellent news - thanks Celine

Hey ! 

Nice catch, I can reproduce on my side too. 
I will create a ticket and we will try to fix it for the next release. 
The only workaround we see is to work horizontally and then rotate. It's bit ...dirty...but depending on what you want to do, it can work.

Thanks for the report !

Céline

Thanks for the extra info - I can replicate that here. I've upvoted your bug report

For me it works on horizontal format  but doesn't work on vertical .    Includind very same voroni node

Unless I am misunderstanding your issue, it seems to work here
