Machinarium black screen regression.

[iiv3]

The bug happens with upstream mesa git.

I'll do a regression search later.

I'm uploading two traces:

1. A trace made with Nine. When it is replayed with WineD3D, it fails with:

01a2:fixme:d3d:swapchain_init The application requested more than one back buffer, this is not properly supported.

2. A trace with WineD3D, when it is replayed with Nine, it works flawlessly.

Edit: I'm saying it is a regression because I've played the game under Linux. According to the savegame the last change is around November 2016. I installed Mesa-11.2.2 that dates at May 2016 and it doesn't work. (that's distro package). My current oldest binary build package is Mesa-17.1.4 from July 2017.

It is very likely that the regression might not be in Mesa, but in Xorg, or Steam Overlay.

It looks like the regression comes from Wine. The following workaround seems to work for a number of games, including Machinarium:

[HKEY_CURRENT_USER\Software\Wine\Direct3D]
"Renderer"="gdi"

However with that setting wined3d stops working.
