When exiting a game, Half Life 1 for instance in Big Picture mode, it'll go back to desktop with Big Picture mode in another view, Steam will be unresponsive unless I go back into Big Picture mode via Unity and wait 30 seconds, terminal shows same stacktrace.
We think we know what is causing this. The fix will be in the next beta release.
Nothing extracted yet.
Running latest beta, closing the Big Picture Mode will hang and a crash dump will be created.
