Summary: SMP problems with Source games
           Product: Wine
           Version: 1.3.4
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Some games with latest Source engine (Alien Swarm, Left for Dead 2) has
sometimes grayed out "Enable multicore rendering" in options menu. But when
It's not grayed out, and I enable it, it works like it's supposed to, giving me
notable fps boost and using both my CPU cores.

But I'm using virtual desktop, to still be able to communicate with my friend
using IM. But sometimes, when I leave virtual desktop and want to return back,
the VD is not redrawing. I can still hear music, game sounds, even blindly open
in-game console nad write quit to exit the game properly. This is not happening
if multicore is disabled in game.
