Hi guys, John Drinkwater just reported a fix to me that makes my 3D driver work correctly on Haiku (window offset error). As it turns out (I think??), Haiku app_server seems to not respect the framebuffer adress given to it (GET_FRAME_BUFFER_CONFIG) by the driver. It really should: it's no requirement of any driver to pinpoint it's framebuffer at offset zero in the cardram. Could one of you tell me if app_server uses fbc for the buffer location or not? And if not, fix it? Thanks in advance for fixing this/looking into this.. Please keep me posted :) Rudolf.
