Previously, a race condition in the TTM (Translation Table Maps) module of the DRM (Direct Rendering Manager) between the object destruction thread and object eviction could result in a major loss of large objects reference counts. Consequently, this caused a major amount of memory leak. With this update, the race condition no longer occurs and any memory leaks are prevented.
