When setting up the state for the vertex buffer, enable_state_for_drawing_buffer tries to keep track of the highest numbered texture unit in use. It then disables any texture arrays for units that were previously enabled if they are greater than that number. However if there is no texturing in the VBO then the max used unit would be left at 0 which it would later think meant unit 0 is still in use so it wouldn't disable it. To fix this it now initialises the max used unit to -1 which it should interpret as ‘no units are in use’ so it will later disable the arrays for all units. Thanks to Jon Mayo for reporting the bug. http://bugzilla.openedhand.com/show_bug.cgi?id=1957 |
