--- Comment #5 from Gabriel Ivăncescu gabrielopcode@gmail.com --- Created attachment 62983 --> https://bugs.winehq.org/attachment.cgi?id=62983 Patch that removes the arbitrary Sleeps
This is the (rebased) patch that drops all arbitrary Sleeps and uses message signals.
I don't know if it will fix this. testbot results are clean, though (https://testbot.winehq.org/JobDetails.pl?Key=45630). But no idea about that page you linked to. To test that page's results, it would have to be committed... Maybe it's worth the hack now?
Oh, one more thing: it easily fails if you press up/down while the test is running. Perhaps other keys as well. No idea what the VM does since it shouldn't, just some food for thought.
