external picture showing corruption
Testing both release and git wayland/weston on R9285.
Using weston-launch from fbcon so it uses weston-drm.
Apart from <a class="bz_bug_link

title="NEW - weston client egl corruption above certain window size since radeonsi: Enable DCC."
href="show_bug.cgi?id=93740">https://bugs.freedesktop.org/show_bug.cgi?id=93740</a> 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.</pre>
