What did you do?

Started playout and activated subtitles.

What did you expect to happen?
Subtitles should be displayed inside of the picture and with non-overlapping lines.

What actually happened?

As soon as the lines contain any styling (colors like c.lime and similar) they are displayed further to the right, out of the picture area. Different text lines are displayed overlapped one over the other, so that text cannot be read. Texts without any styling are displayed fine. With v4.4.1 this problem was not present.
