Comment (by mrvanes at gmail.com):

 Just looked into the problem and found the solution (for me at least).
 I allways have fadeout set to 0 (osd.xml) because my system is too slow to
 have long transparent fadeout (or at least was with old code). The
 behaviour for fadeout=0 is now broken in HEAD:

 Looking into the OSD code I finally reached osdtypes.cpp with the method:
 void OSDSet::Draw(OSDSurface *surface, bool actuallydraw)

 In this method the fadeout/timeouts are handled around line 364:

     if (m_fadetime > 0)


         if (m_fadetime <= 0)
             m_fadetime = 0;
             if (currentOSDFunctionalType)
                 emit OSDClosed(currentOSDFunctionalType);
                 currentOSDFunctionalType = 0;

     if (m_timeleft <= 0 && m_fadetime <= 0)
         m_displaying = false;

 As you can see, in the case of (m_timeleft <= 0 && m_fadetime <= 0)
 OSDClosed is never emitted!
 I have NO idea if setting m_displaying = false is supposed to clear the
 OSD (I guess so) but it obviously doesn't.

 Changing fadeout to 1 in my osd.xml fixed the problem for me.
