Nothing. It's a bug in the matrox driver.
You can upgrade to DirectFB cvs, or use the patch against 0.9.20, or
you can work around it in vo_dfbmga (see below the patch).

To work around the bug in vo_dfbmga add this
bes->SetScreenLocation( bes, 0, 0, 1, 1 );
before the current SetScreenLocation() call in vo_dfbmga.c.
