The previous change removed the special case that matched resources of CompositeClientWindowType and walked back from that to the window pixmap. That was intentional, since that logic was broken anyway. CCWTs don't map 1:1 to references on the backing pixmap; a window redirected by multiple clients (say, by the server since it's on the synthetic visual, and then manually by a compositor) would have a window pixmap refcount of 1, but would have those bytes accounted twice. The right thing is to have Composite wrap window accounting, and add the pixmap bytes once and only once for the redirection reference. Note that the view from the client can still be non-intuitive in the face of Composite. xcompmgr, for example, holds _two_ references to each window pixmap (one each from CompositeNameWindowPixmap and RenderCreatePicture), so a synthetic-visual window will have its bytes split 2/3 to xcompmgr and 1/3 to the server-client. Nothing to be done about that, and at least this way we're not over-accounting. Acked-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Adam Jackson <ajax@redhat.com>
