Bug #: 31365
           Summary: Shaiya FPS drop after ~1 min of game playing
           Product: Wine
           Version: 1.5.9
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major

         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

For about 1 min after running Shaiya I have ~20-25 fps, but after this time (of
doing nothing in the game) framerate drops to 5-10 fps. In the meantime console
is spammed with:

fixme:d3d:wined3d_buffer_preload Too many full buffer conversions, stopping
converting.
