A different basic approach like in > XDarwin or XDirectFB makes more sense to me.
I'm not familiar with how those two X servers operate, so could you help me out by explaining? How do they handle window obscures? How is it different from X11's BackingStore? Note that BS is turned off by default precisely because it's frequently a pessimisation -- too often the BS pixmap is too old, and the X server writes it to the framebuffer only to have it overwritten by the app as soon as it's scheduled. Why are XDarwin and XDirectFB's approaches better? -andy _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
