 Priority:  minor                    |   Milestone:  unknown

 Head revision 20658

 This is not normally a problem for soundtrack subtitles (hence the low
 severity), where the text is merely a little ugly. It can however cause
 irritation when the subpicture has been used to position translations for
 in-picture text (e.g. Japanese/Chinese characters on signs), as these then
 appear in the wrong place and obscuring things they were not intended to

 The problem does not seem to affect normal Xv (non-VDPAU) rendering where
 the subtitles are scaled correctly.
