Comment:

 It is becoming more clear to me. If open attribute table "clear" and
 "unclear" and copy attribute to clipboard, may see that precision of WKT
 geometries is 6 number of digit after comma and "clear"'s and "unclear"'s
 WKT represents of geometries looks the same. But If export this data into
 PostGIS database and take a look on WKT geometries may see that precision
 of WKT geometries is 8 number of digit after comma and "clear"'s and
 "unclear"'s WKT geometries is differently. I guess, that in QGIS precision
 of geometries using in dissolve tools and while rendering is different
 values. Is it possible to do them the same for possibility to distinguish
 nodes more precisely?
