It might be clipped, possibly by a recent Cairo clip, but that would not explain why it's always 1/4 and it might go away with the attached patch, which is my last diff to trunk. I hope I find some free time soon to finish the cleanups. > The WebKit call stack uses surface->Blit but the > gtk-demo stack I guess uses the image provider not > Blit.

Hmm, it might be that the region is not Flip()ed.

Only the Flip() comes to my mind, which could indicate a bug in _begin_draw() and/or _end_draw(). -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-users mailing list directfb-users@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
