Does it still happen with Wine 3.5? There is some (probably small) chance that 1bba7c5705da23586c39de98c764700c5a54fcc0 might help.
I tested this in my environment on Wine 3.5 and still have the blackscreen on launch issue.
The audio works though, I can hear the bird chirping (as is normal) when the game launches and loads a save game. I did this with the d3dx9_43 override in place. I can record my screen using OBS to show what this bug looks like on a user's computer if it makes it a little bit easier to grasp what's going.
This is a regression by the way, since the old workaround doesn't seem to work anymore.
