Description
- open "Add layer", WMS tab;
- connect to http://demo.mapserver.org/cgi-bin/wms? and add the "World country boundaries" layer to a view;
- for instance, zoom on your country.
Result: the layer appears fine initially, while after zooming it's a bit grainy. Instead, the images in tmp-gvsig/downloader are fine.
I attach a screenshot and the image from the relative getmap request:

Curiously, if you select the option 'use of local tile cache' the visualization is good, without 'grainy'

Yes, it works fine using the local tile cache or using a CRS different from CRS:84... I've just discovered that the issue depends by CRS:84 (no auth repository), so it's not a specific WMS one:
