--- Comment #22 from Gabriel Ivăncescu gabrielopcode@gmail.com --- Created attachment 71385 --> https://bugs.winehq.org/attachment.cgi?id=71385 Map the window in UpdateLayeredWindow.
Here's the fix I was talking about. Please test and let me know if it works with Logos 9 Bible also.
I'm not entirely sure if it's better than set_window_pos though...
