Expanding a Live Paint Object Changes Dimensions
Reporting a very frustrating Illustrator bug that has been there since version CS6 at least.
There is a bug concerning the Live Paint tool. Live Paint objects need to be expanded most of the time to develop them further in Illustrator. However, after expanding, the dimensions of the shapes get distorted and this renders the Live Paint tool completely useless for precise drawings or illustrations.
I hope something can be done to eradicate this bug as it extensively hinders workflow of many projects that need to be developed with Illustrator.
Thank you.
P.S. The same happens not only with imported files, but also with Live Paint objects created by native tools.

Ruy, actually, this is intended. Live Paint and Shape Builder both make tiniest simplifications to the art, for the sake of the speed. If you watch the original paper about Live Paint — https://dl.acm.org/doi/10.1145/1275808.1276415 — you’ll hear Paul voicing this out.
More of it, you can make a simple test to see Live Paint breaking the precision. Create a new document and choose millimeters as units (this is important). Create a simple rectangle that has integer dimensions and is placed perfectly on integer coordinates. Convert it to Live Paint object. Expand it. Check coordinates and dimensions.
This bug is less prominent for pixels and inches -based documents, because LivePaint rounds values to fractions of a point.But I vote because this drives me crazy. I believe that the algorithm can keep values and not ditch my data. Thank you for reporting it.

When zooming in (starts becoming noticeable around 4800%) the fills in a livepaint group do not align with the vectors they are made from. I've experienced this on multiple systems, both PC and Mac.

I agree. Main reason I almost never use Live Paint except for rather freeform stuff.
