<div class="moz-cite-prefix">I wonder why it is single buffered. is
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
support for VSYNC. The tearing with X11 is a known issue. We did
investigate to fix this, but the solution becomes too hacky and
cannot be used in production systems.<br>

We are adding VSYNC support in Wayland. eglSwapInterval will be
supported for FBDEV and Wayland backends in the upcoming
release(in january). So Ozone-wayland can take advantage of
this.<br>

I agree Carlos!<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>

There seem to be TWO main issues:<br>

Do you have only 2 issues? Have you double checked if
they are/are not<br>
reported in bugzilla?<br>
<br>
Do you have the detailed step-by-step? I want to
reproduce them.<br>

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>
