The "nv" driver doesn't have anything to do with RENDER.
It's completely out of the picture. I don't see how this
can be specific to the "nv" or "nvidia" drivers. Growing
memory usage in the server is almost always a client resource
leak. You'll notice that the "nv" driver doesn't allocate
any memory outside of initialization.
In 4.1.0 and previous there was a serious pixmap leak in XAA that
happened when purging the cache, which the "nvidia" driver did
frequently when making room for textures when running 3D apps.
I worked around that in 2314 and maybe in the previous version too.
So this shouldn't be an issue, and the "nv" driver was uneffected.
Mark.
