Description

Steps in order to reproduce the issue (found in gvSIG 2.3.1 and 2.4.0 build 2843):

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:
