--- Comment #7 from Rémi Bernon rbernon@codeweavers.com --- Right, I can see the black screen as well with 10.15. Then it is fixed for me with 9cdfa803cd1f971bdf03667c86698685c913e97c, would you mind confirming?
Also possibly there's https://gitlab.winehq.org/wine/wine/-/merge_requests/8975 which could fix some other presentation issues, but it wasn't necessary for me here.
