Thanks for the reply.
1.: Yes, it works flawlessly on the desktop. Trying around a bit the last few days showed that indeed it seems to be a conflicting "on top" setting since it works fine when the game is windowed.
2.: I have written down that wish wrongly. I meant i want to be able to only have the text visible (and maybe menu bars since that cannot be prevented as you said) and have a transparent background (the thing that´s white and you can change the background in the settings). I tried putting a transparent background but that didn´t do the trick.
3.: Too bad
