Bug ID: 46817
           Summary: Steam Big Picture needs
                    d3d11_device_CreateDeviceContextState
           Product: Wine
           Version: 4.2
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: wine-bugs@winehq.org
          Reporter: dark.shadow4@web.de
      Distribution: ---
Split from bug 44120.
Big picture currently errors with
...
Assertion Failed: No D2D device created, possible no GPU supporting D3D10_FEATURE_LEVEL_9_1 or higher was found? Can't create surface
The problem is fixed by adding a stub like
##########
static HRESULT STDMETHODCALLTYPE d3d11_device_CreateDeviceContextState(...)
{
    *chosen_feature_level = feature_levels[0];
return S_OK;
}
##########
This makes big picture mode open, but you still have a blackscreen due to
missing d3d10 effects support. But judging from the sounds, it atleast works
instead of crashing.
