From 63318d34acd4a5edb271d57adf3b01e2e52552f8 Mon Sep 17 00:00:00 2001 From: Nanley Chery Date: Tue, 15 Nov 2016 16:42:23 -0800 Subject: [PATCH] mesa/fbobject: Update CubeMapFace when reusing textures Framebuffer attachments can be specified through FramebufferTexture* calls. Upon specifying a depth (or stencil) framebuffer attachment that internally reuses a texture, the cube map face of the new attachment would not be updated (defaulting to TEXTURE_CUBE_MAP_POSITIVE_X). Fix this issue by actually updating the CubeMapFace field. This bug manifested itself in BindFramebuffer calls performed on framebuffers whose stencil attachments internally reused a depth texture. When binding a framebuffer, we walk through the framebuffer's attachments and update each one's corresponding gl_renderbuffer. Since the framebuffer's depth and stencil attachments may share a gl_renderbuffer and the walk visits the stencil attachment after the depth attachment, the uninitialized CubeMapFace forced rendering to TEXTURE_CUBE_MAP_POSITIVE_X.
