--- Comment #6 from lilydjwg@gmail.com --- It turns out that the real window is covered by a freezing window for me....After minizing and reshow the window, that weird window is gone. Maybe some issue only seen with the Awesome window manager.
However, there are other issues. I've submitted a new issue: https://bugs.winehq.org/show_bug.cgi?id=38081
