From 7ac0873b4a75dde9de2b01ca11fb97aac0ffc128 Mon Sep 17 00:00:00 2001 From: Philip Rebohle Date: Thu, 24 Oct 2019 20:58:15 +0330 Subject: [PATCH] vkd3d-shader: Use full write mask for variables for array built-ins. Private variables are always vec4, so using a sparse write mask here will lead to invalid code being generated when accessing the variable.
