Youtube titles going off the screen

My Youtube subtitles tend to go off the screen (ie. like they’re in notepad, no line breaks) so I can’t see the majority of the text. Hitting “alt option” (I’m on an Apple) temporarily fixes it, but it quickly reverts to the no line break version. This occurs on different computers, though all of them with Chrome. This doesn’t happen for me with Netflix.

Is this a known bug? Have any of you found a fix?
