Right, without a flip, the dfb stack isn't aware that the window's area must be updated. So the screen is not updated until someone else asks for a refresh, which could create some incoherent display depending on the area to refresh. About the single buffer settings, there is 2 fields you can setup when creating a new window. In the DFBWindowDescription : 'caps' and 'surface_caps'. Make sure to set not set the DWCAPS_DOUBLEBUFFER flag in 'caps' field and to not set DSCAPS_DOUBLE and DSCAPS_TRIPLE in the 'surface_caps' field. > bye > shiva > > On Tue, Mar 2, 2010 at 5:46 AM, Anders Bakken > <anders.bak...@nokia.com> wrote: > I have two questions about IDirectFBWindows. > > If I have a single buffered window do I still need to call > Flip() to > make changes visible (I would expect not) > > How can I make single buffered windows?
