            Bug ID: 92236
           Summary: [ColorTiling2D] R600 BARTS radeon: pipe_context->clear
                    with color tiling enabled doesn't immediately affect
                    color buffer
           Product: Mesa
           Version: git
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: siro@das-labor.org

There's an open Gallium nine bug: https://github.com/iXit/Mesa-3D/issues/138

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: https://github.com/iXit/Mesa-3D/

That's correct. nine needs to resolve the clear using the pipe->flush_resource
hook.

Fast clear only works with tiled surfaces.

IIRC that's currently a software fallback.
