Description

I have a WMS. When I set transparency in QGIS, the layer becomes very ugly - colours become pseudo colours etc. See attached for the result of request QGIS makes to the WMS, and what QGIS shows on the screen for just 1% transparent and 70% transparent.
Looking at the requests made to the WMS - they're all requesting the exact same file, so transparency is being done client side.

My WMS is internal only and cannot be shared. Also my QGIS doesn't have access to internet so I can't test external ones.

can't you install and test qgis in a pc outside of your work environment?

Possibly, but that won't let me test my given URL.

but we will know if is a general issue or is about your wms server.

The server is a GeoServer 2.3.5 install
This happens with QGIS 2.0

Sorry, it's still internal only I'm afraid. Hopefully soon (ha!) our security folks will finally approve it (or even respond!).
