Have you done any research to validate the usefulness of the ComparingUpdateTracker? Personally, I found that, in Xvnc, it wasn't catching very many duplicate updates, and the dupes it was catching would not have significantly slowed down performance (they tended to be areas of solid color, which the Tight encoder already optimizes out.) The CUT might be beneficial in cases where an ill-behaved app draws the same frame over and over again, but that is a corner case, not the norm. I could also see it being beneficial in x0vncserver, if the polling rate is faster than the update rate of the app, but that's definitely a corner case as well. Thus, I disabled the CUT by default in the next-gen version of TigerVNC. The fact that you spent time optimizing it tells me that you must have an app that can take advantage of it. I'm interested to hear the details.
