MKV font is an outline and can't be read in dark scenes

I use MakeMKV to rip my dvd’s, I find that forced subtitles do not always work, so during scenes in another language I have to turn subtitles on then turn them off after the scene. Also I found recently particularily in x-men first class, the subtitles were white when they were speaking english but when they switch to german the font becoms just black outlines of the words and can’t be read in the bottom of the shot is a dark colour, is this a Live Hub issue or a MakeMKV issue, and how to correct it.

Thanks

I’ve never seen that happen on the Live Hub…  What version of Firmware are you using?
