Have a look at the diagrams on this page: http://udig.refractions.net/confluence/display/DEV/07+Edit+Tools

The origional JTS geometry is processed into a data structure for display; this step (simplification?) is dependent on the zoom level; one vertex on screen can represent several JTS coordinates in the origional geometry). This step should be done again if the user zooms in or zooms out; but currently it is only done once.

We cannot reproduce this bug in 1.2 -trunk and 1.2.0-RC1. We think it was solved with the patch applied in http://jira.codehaus.org/browse/UDIG-965
