I think is already fixed a long time ago, see https://bugs.winehq.org/show_bug.cgi?id=44084
Is the bug still present in current wine?
Yes.
I just retested with today's git master and no the app doesn't show it's GUI. With commit c222b86a528e71207bbde57e177ff5be3ee211dc reverted app seems to work. I believe this is a different issue.
