Testing both release and git wayland/weston on R9285.

Using weston-launch from fbcon so it uses weston-drm.

Apart from https://bugs.freedesktop.org/show_bug.cgi?id=93740 which can be worked around, rendering is good when compositing.

If I run something that allows weston to enable direct scanout there is slight corruption. kodi and mpv are the only ways I know to do this.

If I do something that changes back yo compositing the corruption goes, taking a screen shot/recording or zooming in will all "fix" the corruption.

I am inferring direct scan out is happening as I can't change transparency + the man page for weston-drm says it will be used where possible.

Tried going back in time with mesa to see if it ever worked, but I started hitting places where either weston wouldn't start or I always got compositing so no corruption but I could change transparency.
