How to hide new-line characters in Scintilla?

Question

I'm creating a dark theme for a Scintilla based editor. I've managed to define all styles as I wanted, except for the line endings. In other words, despite all the text in my editor being showed on a dark background, at the end of each line there's a small white-filled rectangle.

I believe this rectangle is related to line-feed character, because even empty lines have it. But no other control characters are being displayed.

So, how can I get rid of this white rectangle?

I've tried to change the ControlCharSymbol to other values (under or above 0x20) and got no result.

Note: I've just noticed that the same occurs for white-spaces and tabs if they are set to be INVISIBLE. If they are set to be visible, Scintilla shows them as '.' and '--->' using the colors I've defined.

If you've already set the background for all the styles defined by the lexer, you might also try setting the background for STYLE_DEFAULT.

If that doesn't work, the background can be set globally for all whitespace using SCI_SETWHITESPACEBACK.
