From d866abeffc7e4a29736fa35fb8ac09c3a28a44d6 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 13 May 2009 18:18:29 -0700 Subject: intel: Use GL_FRONT_AND_BACK for stencil clearing. This comes from a radeon-rewrite fallback fix, but may also fix stencil clear failure when the polygon winding mode is flipped. --- src/mesa/drivers/dri/intel/intel_clear.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/src/mesa/drivers/dri/intel/intel_clear.c b/src/mesa/drivers/dri/intel/intel_clear.c index eb0d890f477..488db2cf452 100644 --- a/src/mesa/drivers/dri/intel/intel_clear.c +++ b/src/mesa/drivers/dri/intel/intel_clear.c @@ -256,7 +256,8 @@ intel_clear_tris(GLcontext *ctx, GLbitfield mask) if (this_mask & BUFFER_BIT_STENCIL) { _mesa_Enable(GL_STENCIL_TEST); _mesa_StencilOp(GL_REPLACE, GL_REPLACE, GL_REPLACE); - _mesa_StencilFuncSeparate(GL_FRONT, GL_ALWAYS, ctx->Stencil.Clear, + _mesa_StencilFuncSeparate(GL_FRONT_AND_BACK, GL_ALWAYS, + ctx->Stencil.Clear, ctx->Stencil.WriteMask[0]); } else { _mesa_Disable(GL_STENCIL_TEST); -- cgit v1.2.3
