From 0b73c86b8030a7f7cb35fc85c83eff7f2b8c24a4 Mon Sep 17 00:00:00 2001 From: Henri Verbeet Date: Mon, 26 Mar 2018 19:06:08 +0430 Subject: [PATCH] mesa: Inherit texture view multi-sample information from the original texture images. Found running "The Witness" in Wine. Without this patch, texture views created on multi-sample textures would have a GL_TEXTURE_SAMPLES of 0. All things considered such views actually work surprisingly well, but when combined with (plain) multi-sample textures in a framebuffer object, the resulting FBO is incomplete because the sample counts don't match.
