Description
latest qgis 3.2.1, windows 7.
I run geometry checker for duplicate nodes with tolerance 1e-6 and it founds a lot of duplicates but when I check them there is only one node, no duplicated ones.
If I change tolerance the number of errors changes. With 1e-10 no errors was found.
It shows duplicates for polygons and linestrings. Can somebody check it?

Possibly a problem with rounding when using very small tolerances. What is the problem in using a bigger tolerance?

the biggest allowable value 1e-3 still produces wrong errors.
I've changed project projection to epsg:3857 (previous was epsg:4326) nothing changes.
