Thanks, https://gitlab.winehq.org/wine/wine/-/merge_requests/6520 should fix this.
Dear Rémi Bernon,
I tried the patch with the following versions of the game: original demo version GOG.com (v1.02 game version) Steam (v1.04 game version)
The reported problem with the size of the screen is fixed in all of them, thank you so much. However there is something wrong with the patch that makes the mouse pointer stuck (not moving) in the main menu in the demo and the GOG version of the game. This doesn't occur with the Steam version. Would you mind trying the demo with MR6520 applied to see if you can reproduce that? Thanks in advance.
