--- Comment #1 from VaL Doroshchuk <valkov at yandex.ru> ---
It is an issue due to:
> Only one client at a time can select a ButtonPress event, which is associated with the event mask ButtonPressMask.

And QWindow does subscribe to receive a ButtonPress event, and this avoids
receiving _any_ events by vaapisink.
