--- Comment #12 from Zebediah Figura  ---
The deadlock visible from the last logs should be fixed by
https://source.winehq.org/git/wine.git/commitdiff/84e55192fa2d6610acac2edfef3421cba0705331,
but there are some regressions in the sample grabber, and even with those fixed
it still hangs—looks like a deadlock between the main thread and the sample
grabber callback, which is waiting for messages and never returns. I'll keep
working on it.
