They the same vector in 2 instances (ie. 2 gis.m vector layers - one
duplicated from the other). They should be identical. The way they are
in d.m.

They should perfectly cover one another. Both layers are the same
vector file! So why should they be displayed at different zoom levels
within the same display? gis.m, provided the conditions I describe,
displays the 1st instance in one zoom level, and the 2nd instance in
another zoom level, while within the same "Map display" they should
cover each other. This is wrong.

Just try my procedure. Easy to replicate. In d.m it works OK. Only
gis.m is affected.
