      Seems insanely high for just rendering the desktop.
      Yes. The desktop frame rate should be in sync with the screen. If the desktop can't deliver frames at less than 12.97 ms then it only takes a little bit of overhead from other apps to make the desktop stutter on a 60hZ screen. I have noticed this on my desktop with a Core i7 and a Nvidia GTX 1060.
      This is indeed very poor performance. I really hope they will focus on this, because the desktop should'nt be in the way.

          It's that, and it's also the poor input handling: https://bugzilla.gnome.org/show_bug.cgi?id=745032

            It is. there is something terribly wrong here still.

            Also, as a side note same bug (the one still there) is hitting addons that show things in intervals. I had the system monitor addon that drew at the top panel and it caused my mouse to jitter as it refreshed. Was a nice find when I removed it. I suspect it's a similar issue. I wouldn't consider this bug fixed with this kind of performance.

              yes, it is enough, but what if I launch an application?
              the application needs to render graphics, but the pipeline is already working on rendering the gnome desktop and the FPS fall inevitably down

                Interesting. I'll definitely be sticking with Xorg for a bit given all the problems on Wayland. Reading this bug report it looks like this only impacts X11 applications?

                  Man, the state of things seems pretty bad in big desktop land. I have a 144Hz display as of recent, and I can't imagine how frustrating it would be if the desktop (before any applications!) was already limiting my framerates to less than 60fps. Happy to be running dwm with tearfree X. ;- )

                    No, I'm on X11. (With NVidia drivers.)

                      I'm on X11. It runs fine for a couple minutes after logging in, but about 2 minutes in, the stutter hits and never stops.
