Question: running GTK apps in a Linux VM under Parallels in “coherence mode” provides a better user-experience (in several ways: smoother, better accessibility, etc.) than running a native-macOS-compiled GTK apps under XQuartz does. Why is this?<p>• Is it a difference of display model? Where/when compositing is done? Is X11 really that high-overhead of a protocol, that putting a “compositor in your compositor” like Parallels’ video driver does, can do better?<p>• Is it that macOS GTK apps are relying on macOS as the window manager / window decorator (which those apps were never heavily tested for), while “coherence mode” GTK apps are bringing their own DE (GNOME or what-have-you) along with them onto the macOS desktop, which “knows” what to do with those apps much better?<p>• Something else I’m not thinking of?
