At the end of every line in Scintilla is a rectangle that may be painted in 
selection colour if that line end is selected. It is as wide as an average 
character.

When that line end is not selected the rectangle is drawn in the background 
colour of the line end which is often the global background colour so not 
noticeable. However, when there is a full line element like a line comment 
or preprocessor directive with a background colour, this is visible.

Example of some Lua code with a comment background colour at
https://www.scintilla.org/EOLBackground.png
In the example each line ends with its final graphical character - there is 
no line-end whitespace.

This is very old behaviour and may have been intentional but I'm unsure now 
whether it is reasonable. I am inclined to draw this area in the global 
background colour like the remainder of the line unless the style includes 
the EOLFilled option. The selection colour will still be applied over this 
when the line end is selected.
