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.

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.
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.

I agree Carlos!
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.
There seem to be TWO main issues:
Do you have only 2 issues? Have you double checked if they
are/are not
reported in bugzilla?
Do you have the detailed step-by-step? I want to reproduce them.

Daiane,
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.
