      it because of the memory consumption for a second buffer? The
      buffers could be flipped, eliminating any need for blits, so the
      memory bandwidth should not be an issue.<br>

      <div dir="ltr">i.MX6 X11 EGL is single buffered and there is no

        We are adding VSYNC support in Wayland. eglSwapInterval will be

                  I agree Carlos!<br>
                  <br>
                  This is a show-stopper for applications in markets
                  like the Digital Signage market - which could be huge
                  for the i.MX6. The i.MX6 could be the best "media
                  player" out there but the problems related to video
                  playback in a browser (like Chrome/Chromium) needs to
                  be solved wih the highest priority and at the highest
                  level.<br>

                Do you have only 2 issues? Have you double checked if

                Do you have the detailed step-by-step? I want to

            try out the attached HTML example. It draws a white vertical
            bar on a black background, and moves that bar horizontally.
            Run this on an imx6 in Chromium in X11, and you will see how
            severe the tearing is.<br>
