Flood Fill Sampler Node is Very Unstable

[kq1231]

Hi there! I hope you are doing great @njbrown!
I was using TextureLab yesterday and I found out a new node called "Flood Fill sampler". This is a great node that can be tile an image in a particular way with amazing parameters such as random rotation, random scale, and random position.
However, when I started using it, I found it very unstable. It was giving me some problems.
First of all, if you try to use random scaling, it clamps the output. This is the original image:

Now, this is what happens with random scaling:

Adjusting the precision hasn't helped. I also have seen that there is a problem with the random rotation:

It creates some weird lines (see the tiles at the side).
