<pre>There's an open Gallium nine bug: <a href="https://github.com/iXit/Mesa-3D/issues/138">https://github.com/iXit/Mesa-3D/issues/138</a>
It looks like pipe_context->clear called with PIPE_CLEAR_COLOR isn't applied
immediately to the buffer.
As nine mimics swap-chains, the buffer is reused after some frames resulting in
"delayed" presentation.
The problem doesn't exist with R600_DEBUG=notiling and it doesn't exists when
using pipe_context->clear_render_target instead.
Tested with mesa git: <a href="https://github.com/iXit/Mesa-3D/">https://github.com/iXit/Mesa-3D/</a></pre>
