[Bug 42819] The Witness requires alpha-to-coverage

https://bugs.winehq.org/show_bug.cgi?id=42819

--- Comment #9 from cladmi  ---
Tested with the last wine-git version, and it is fixed.

I added the registry entry Software->Wine->Direct3D->MultisampleTextures as a
DWORD = 1 and ran the game with "2x MSAA".
Without MSAA you get the blocky rendering as before.

Tested with different resolutions, settings, MSAA levels.
Grass looks as "correct rendering" and puzzles can be seen from any distance.

Thank you.
