Need some help: while playin' .mkv files with subtitles sometimes player shows not only the text but some special symbols (letters and digits).
This bug appears in case of "complicated" subs (when text must be placed in different sides of the screen: e.g. some text at the bottom and some - at the top).
It looks like this symbols are some commands for decoder, like tags in html or xml documents - but i'm not sure.
I have such a problem only with linux players (SMPlayer, Kaffein, VLC), in Windows with K-Lite CP 4.0 all subs are displayed correctly.
