From 1c6aa6599efd9b5cca270bef2e53fd7ac5f31647 Mon Sep 17 00:00:00 2001 From: Andreas Hartmetz Date: Sun, 13 Apr 2014 22:29:35 +0200 Subject: translate_sse: Use the correct buffer index in this fast path. It is possible that there are multiple input buffers but only one is relevant for translation. Then there will be only a single translation group, which might need to source data from a buffer index != 0. Fixes wrong vertex shader inputs as observed while debugging with an application and driver combination that requires translation of a vertex attribute in a non-trivial set of attributes and input buffers.
