--- Comment #66 from Dreamkey ghost_anarky@hotmail.com --- Created attachment 72700 --> https://bugs.winehq.org/attachment.cgi?id=72700 xprop output of the two screens
Issue still there with here with Wine staging 7.11, but thanks to the imaxm's work-around I think I found the root issue: the game (or Wine) renders *two* screens.
The first is the black screen everyone sees, which can not be controlled by my WM (Awesome WM): it's not on the taskbar, I can't close it, it's just on top of everything else. The second is the game that you can see after the work-around.
It's even more obvious when you use dgVoodoo to have the characters in higher resolution, there is a 800x600 black square on top of the game that uses the defined resolution.
I added the xprop output of the two screens, if it helps.
