From 0d56ad10a86372f55ce0bcf25c7aabc0f9e81a0f Mon Sep 17 00:00:00 2001 From: Owen W. Taylor Date: Wed, 6 May 2009 14:44:16 -0400 Subject: [PATCH] When clearing the stencil buffer, don't use a two-sided stencil In radeon_clear_tris(), when clearing the stencil buffer, pass GL_FRONT_AND_BACK to _mesa_StencilFuncSeparate(), to avoid triggering a software fallback on r300 and below. https://bugs.freedesktop.org/show_bug.cgi?id=21601 --- src/mesa/drivers/dri/radeon/radeon_common.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/mesa/drivers/dri/radeon/radeon_common.c b/src/mesa/drivers/dri/radeon/radeon_common.c index 8b5b892..ee3ee9c 100644 --- a/src/mesa/drivers/dri/radeon/radeon_common.c +++ b/src/mesa/drivers/dri/radeon/radeon_common.c @@ -1429,7 +1429,7 @@ void radeon_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); -- 1.6.2.2
