Subtitles went large like crazy!

[giandoblues]

Hi there,

I was watching a .mkv file and all was good, I probably pressed some wrong combination and now my subtitles are waaaay larger on my screen, making them almost unreadable. If I go in the subs settings, I cannot change the font size!
This happens with the whole episodes of this specific series I am trying to watch - and trust me, it worked good previously! I tried with another .mkv file and subtitles look normal.

Any suggestions?
Thanks!
