Re: [agl-dev-community] Tips for debugging GPU acceleration.

Thanks - that seems to do the trick.
I can't find where in the agl repo that is set. The recipe seems to be in:

  meta-agl-cluster-demo/recipie-graphics/wayland/weston-ini-conf/virtual-landscape.cfg

but I can't see where the "transform=270" got added.

Visually it looks a lot nicer now although I could still do with
getting rid of the quite large AGL lower banner which is cropping out
the main display.
