A processor executing a display driver receives a new image object that has one or more identifiers. The processor makes a first determination as to whether the new image object matches one of a plurality of previously received image objects based on the one or more identifiers. If no match is found, the processor makes a second determination as to whether the new image object matches one of the plurality of previously received image objects based on comparing a hash of the new image object to hashes of the plurality of previously received image objects. If a matching previously received image object is found from either the first determination or the second determination, a reference to the matching previously received image object is sent to a client. If no matching previously received image object is found, the new image object is sent to the client.
