Hello,
I have found that the DDraw/DirectX 7 over WineD3D patch introduces a regression. Heroes of Might and Magic IV now displays a menu in the upper area of the screen, something it is only supposed to do in windowed mode. The game is then moved a little down, so the bottom of the screen disappears. If the game's resolution is changed, it displays correctly, but if it then is changed back to the resolution it had when it started, the menu appears again.
How it works with current CVS http://appdb.winehq.org/screenshots.php?appId=1229&versionId=1638
