Summary: When Compositor finishes compositing, it destroys EffectsHandlerImpl, which in its turn tries to unload all effects. But there is a problem... EffectsHandlerImpl has platform-specific hooks to ungrab keyboard and also stop mouse interception. Given that any call made to a virtual function in the destructor of a base class(EffectsHandlerImpl) won't go to a derived class(EffectsHandlerImplX11), keyboard won't be ungrabbed even if effect that grabbed it is already gone.
