SetDrawingFlags(DSDRAW_NOFX)? > tmpSurface->FillRectangle(0,0, Xres, Yres); > tmpSurface->Flip(); // Flip the field These two methods (if you use DSDRAW_NOFX in the latter case) should provide identical results (and use the same code paths).

You can use the no-hardware directfbrc option to force software rendering. -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ _______________________________________________ directfb-dev mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
