Comment (by Jim Stichnoth <stichnot@…>):

 Regarding the frame dropping problem.  By using "git bisect", it looks
 like the problem may have been introduced in [8f757eeaf].  If I revert
 that checkin (along with subsequent checkins [5787e9c52], [6ac09f0cd], and
 [3c441c2c2]), the frame dropping appears to go away.

 I haven't dug into the MythUIText changes, but I suspect that calculating
 the text layout has become substantially more expensive, such that laying
 out all the portions of a caption exceeds the frame time.  Especially on
 an ION/Atom frontend.  (Each newline or color/italics/underline change
 results in an additional MythUIText object.)

 Maybe there's a way to use MythUIText objects for captions that avoids the
 new expense in [8f757eeaf]?
