 > Options:

 try to improve them.

 This is probably worth doing anyway, as it will improve overall UX

 > 2. Put OSD rendering in a separate thread. This may require a new osd
 renderer object and ways of synchronizing information. Simply using the
 existing OSD object in another thread does not work, for several reasons.

 > 3. Use the OSD::Draw method instead, which draws into a memory image,
 and then use OpenGL to display that image. The OSD::Draw is used by
 software merge and is fast.

 Which of these 2 is the "right way"?
 I currently lean towards #3 as that will be the easiest in the short term,
 but if it's not great in the long term then #2 becomes more appealing....
