Mesa had some problems dealing with the special behaviour of attribute 0 in some cases which have now been fixed in master (41eef83cc030e7) and the 9.2 branch (24d1949ddcd) The problem in cogl was that we were always relying on the gles 2 semantics that there is nothing special about generic attribute 0. With big GL though you're required to associate attribute 0 with your position attribute. The attached patch makes sure we always explicitly call glBindAttribLocation to bind cogl_position_in to location 0 which seems to fix the remaining failures for me. -- Configure bugmail: https://bugzilla.gnome.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ Wayland-bugs mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/wayland-bugs
