Summary: Counter Strike Source: Error "failed to lock vertex
                    buffer in CMeshDX8::LockVertexBuffer"
           Product: Wine
           Version: 0.9.48.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When trying to play Counter-Strike: Source, the menu attempts to load, and then
the system crashes with a window popping up that states "failed to lock vertex
buffer in CMeshDX8::LockVertexBuffer"

This is on a fresh boot, so rebooting would not solve the issue.

This ONLY occurs having "-dxlevel 70" as a launch option. Dxlevel 80 makes the
game load fine.
