Sorry to bother you, but I’ve run into a rather frustrating issue — the XOR result is not clean.
I have confirmed that
- the database units (dbu) are the same,
- both layouts are flattened,
- the polygon coordinates are identical,
- all shapes are rectangles.

Please put in some effort to create a minimal working example.
You can use select/delete/undo delete and "save only visible layers" to create small testcases from the largest of chips.
And be more specific in your reporting.
Are you using Tools->XOR and if so, what settings ?
Or are you using the drc engine ? In which case, show what runset you're using.
