Basically, Intellij is making my code extremely hard to read by underlining lots of my code. It kind of makes a chess board on the left of my screen as well! =>

I have looked through the code editor settings but I can’t find one under scala which controls these underlines. I am using the twilight theme but I have only just noticed the issue. Any ideas Intellij buffs?
IntelliJ 12:
Settings -> Editor -> Colors & Fonts -> Scala -> Implicit Conversions
Uncheck “Effects -> Underline”
IntellIJ 11 or Before:
Settings -> Code Style -> Scala -> Other -> Other settings -> Highlight methods added via implicit conversion.
However anyway it’s usability problem of this feature. Something different should be done to highlight implicit conversion for such places.
