According to kernel logs, and time of this logs, this is some where bethwene the bug in firefox and compiz. At the time I produced this video for bugreport: http://videobin.org/+281/2il.html and switched compiz off and on. The problem, if i reproduce this steps i get other log: [14396.675124] [drm:i915_gem_object_bind_to_gtt] *ERROR* Attempting to bind a purgeable object [14473.046399] [drm:i915_gem_object_bind_to_gtt] *ERROR* Attempting to bind a purgeable object _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
