From c53705ed7b89e5a2586b534508182de9c72452ea Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 17 Jun 2009 07:58:35 -0600 Subject: [PATCH] GLX: attempt to fix glean makeCurrent test cases. Two parts to this: One we don't keep pointers to possibly freed memory anymore once we unbind the drawables from the context. Brian I need to figure out what the comment you made there, can we get a glean/piglit test so we can fix it properly? If the new gc is the same as the oldGC, we call the unbind even though we just bound it in that function. doh.
