From cee66dd2aa182ba30130bef3298444667753b051 Mon Sep 17 00:00:00 2001 From: Tim Rowley Date: Thu, 3 Nov 2016 13:33:13 -0500 Subject: swr: [rasterizer core/jitter] fix alpha test bug Alpha from render target 0 should always be used for alpha test for all render targets, according to GL and DX9 specs. Previously we were using alpha from the current render target.
