[PATCH v6 0/4] MR3319: evr: Leave critical section before waiting for streaming thread.
I'm not sure how could I test this behavior, right now the test I wrote works but there are times where it doesn't enter into the deadlock. -- v6: evr: Remove process input handling from streaming thread. evr: Don't lock presenter allocator when calling NotifyRelease https://gitlab.winehq.org/wine/wine/-/merge_requests/3319
