There are two cases covered here: 1) The GstWlDisplay forces the release of the last buffer and the pool gets destroyed in this context, which means it unregisters all the other buffers from the GstWlDisplay as well and the display->buffers hash table gets corrupted because it is iterating. 2) The pool and its buffers get destroyed concurrently from another thread while GstWlDisplay is finalizing and many things get corrupted.
