[Bug 50950] Her Story: intermittent hangs/crashes when video stops playing

[WineHQ Bugzilla]

--- Comment #4 from Zebediah Figura  ---
My guess is that the crashes get less likely because DXVK performs
UpdateSubResource() asynchronously [and therefore is stuck inside of
UpdateSubResource() for less time]. We should do that in wine as well, although
it doesn't leave me confident that there's not another bug keeping the game
from synchronizing correctly.
