[yocto] Weston Failure

Western or Weston? I never saw anything as western, considering GFX
(you mentioned western twice)?! Probably you meant Weston.

Weston is Wayland backend, actually, Wayland is more of a GFX
communication protocol, and Weston is one of the several compositors
behind Wayland. Other well-known compositor is Mutter, as common
example.

It seems that you have timing synchronisation problem (race effect)
between EGL's (Embedded Graphic Library) loadable modules components,
and the best place to ask about such things is exactly:
http://wayland.freedesktop.org
Bug reports to:
https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=weston&version=1.9.0

Best Regards,
Zoran
