Comment (by jpilk):

 I'm not clear if this report is based on one of the new patches, but I see
 the same with recent unpatched master, v30-Pre-11d426bd49b.  I rarely use
 live tv and so have never encountered it during my normal use. BBC Radio
 3, DVB-T with the interactive program info GUI displayed at playback
 start.  It's an easy test, if you can get the signal...

 Entering live TV via the Guide and "Watch this channel" then Escape soon
 after playback starts:
