Following your advice I tested a Poky image with Wayland/Weston 1.6.0
and the screenshot was working fine on it.

Yes, the hardware graphics acceleration in enabled for Weston 1.6.0 on
My research shows that the issue is specific for i.MX6. The screenshots

Weston without it I can successfully capture screenshots.
