Summary: Portal fails to start
           Product: Wine
           Version: 1.3.20
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I tried to launch Portal 1 via Steam. The producer's logo works, then on the
light/gray screen the "Loading" text is mixed up (stripes + shifted so it says
"ngLoadi"). After a couple of seconds Portal closes itself (Stream stays
installed).
I'm running on core i3 with integrated gpu.

Logs attached.

Is there any other information I can provide?
