| Interesting!
uDig tries to pay careful attention to what GeoWebCache says it is doing with respect to coordinate reference system. If both the map display and the geowebcache are in 4326 then no scaling should occur.
Please note that uDig *will* allow you to choose any zoom at all; so the closest set of tiles will be featch and stretched onto the screen. If the CRS is the same this should just amount to a change of scale; and not a stretch or sheer.
uDig is willing to request tiles and actually reproject (well resample) them onto the screen as well.
Would you like to open a bug report (say in uDig to start with) and include some screen snapshots so we can get discussion going?

Yesterday I tried to add a cached WMS layer to udig served by a local geoserver instance. I activated the geowebcache and added the following context-param values to the web.xml file:
<!-- GeoWebCache configuration -->
<context-param>
<param-name>GEOSERVER_WMS_URL</param-name>
<param-value>http://localhost:8091/geoserver/wms?request=GetCapabilities</param-value>
</context-param>
<context-param>
<param-name>GEOWEBCACHE_CACHE_DIR</param-name>
<param-value>/user/myName/gwc</param-value>
</context-param>
When I added the layer to udig (Layer->Add->WMSC) i got resulting image rendered like you can see in attachment. In the screenshot you can see I added to layers. The standard WMS layer (http://localhost:8091/geoserver/wms) and the cached one (http://localhost:8091/geoserver/gwc/service/wms).
Do I have to configure uDig (e.g. tile cache size) or geoserver or even geowebcache? The layer is served in EPSG:4326 and the client Map hat the same CRS set.
Do you have any suggestions? Maybe it cold be a bug but I have no clue where (udig, geoserver or geowebcache).
Kind Regards,
Frank
