You're possibly right, but I would still consider that behaviour as a bug,
particularly when it isn't documented anywhere. For example, I don't see any
call for synchronising in the API (apart from actually doing a drawing
operation).  All I can say is that I find it highly surprising to have the
state of my DirectFB surface changed by cairo, and to not have that state
restored when I call cairo_restore().  As there isn't a formal spec, and the
documentation (both the API reference manual and the comments in the source
code) have nothing to say on the subject, I felt that this was more of a bug
than anything else.
