From 2223615e0a897434b41f86d22c41cb5dc9f8d67a Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 11 May 2009 09:46:56 -0600 Subject: mesa: Fixed a texture memory leak The current texture for any particular texture unit is given an additional reference in update_texture_state(); but if the context is closed before that texture can be released (which is quite frequent in normal use, unless a program unbinds and deletes the texture and renders without it to force a call to update_texture_state(), the memory is lost. This affects general Mesa; but the i965 is particularly affected because it allocates a considerable amount of additional memory for each allocated texture.
