The fix is now live in master.  Thanks for pushing on this, as you found a
Qt5 issue that would have hit others as well.

As a special thank you :), I also made a change so you can control
background transparency on teletext subtitles, e.g.:
  <shape   name="teletext" from="provider">
    <fill color="#000000" alpha="128" />
  </shape>

The "color" spec is ignored, but the XML parser requires it.  For teletext
subtitles (but not the rest), you still need to restart mythfrontend for
osd_subtitle.xml changes to take effect.
