Yes but that isn't necessrily a good idea as it will waste memory and add overhead to flippng (compared to running directly on the layer's surface). My UAE DirectFB port has windowed+fullscreen support using layer/window APIs. The only ugliness that I really don't like is with input handling. I have to handle both window and input events depending on which mode the app uses. > additionally, is any hardware acceleration lost when > running in windowed mode? No. Well provided that the window has the same pixel format as the layer or the hardware supports format conversion. > > > is the radeon driver not capable of such an overlay layer? > > > > The driver doesn't support it.

Judging from the XFree86 driver source the overlay is very similar to r128's overlay so it should be quite easy to get it working. -- Ville Syrj�l� [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-users" as subject.
