The view shows information about the currently allocated buffer objects. The list of buffer objects can be filtered by usage, or by the last bound target column (for GLES only). The bottom part of the view shows the size of the currently selected buffer objects. If no buffer object is selected, the size of all the displayed buffers objects is shown.
To filter the view to show only the buffer objects with a given usage or last bound target, use the Filter box. For example, type transform into the box and the view will only show you the buffer objects which have 'transform' in the usage field. See Searching and Filtering in MGD for more information.
