            Bug ID: 43082
           Summary: adapter->vram_bytes = 128 * 1024 * 1024
           Product: Wine
           Version: 2.8
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs(a)winehq.org
          Reporter: winetest(a)luukku.com

dlls/wined3d/directx.c#l6590

function

static BOOL wined3d_adapter_init_nogl

few lines later

adapter->driver_info.name = "Display";
6598     adapter->driver_info.description = "WineD3D DirectDraw Emulation";
6599     if (wined3d_settings.emulated_textureram)
6600         adapter->vram_bytes = wined3d_settings.emulated_textureram;
6601     else
6602         adapter->vram_bytes = 128 * 1024 * 1024;
6603 

In worst case wine sets the gpu memory amount only 128 Mb. That's really low
even for cpu integrated gpus nowadays. I don't know the limits of DirectDraw
applications or Games, but would think that they would handle higher amount
just fine.

Is there a real program being affected by this?

As a "worst case" a moderate amount like 128MB makes sense for most old apps.
Setting higher amounts can make programs perform worse.  e.g. see bug 42126.   

Like Bruno, I'm also interested to know which app is affected and how.

That is only executed when there is no OpenGL support or it's been explicitly
disabled via the DirectDrawRenderer registry key. In that case defaulting to
128 MB seems perfectly fine to me (actually it might be too much, if anything).

Bottom line, I don't see any bug.
