Dear Maintainer,
when opening LaTeXila, which has 4 files open from the last session, I noticed that two files have different line heights displayed which means that the line numbers (and text lines of my TeX document) vary a bit in their vertical position (the horizontal position seems to be reliable). The visual difference starts in line 4 and results in a difference of more than a whole line at the bottom of the monitor (lines 47 and 48 resp.).
I reopened LaTeXila to see wether it's an issue of opening a file during a session, but I didn't see a change of the positions of the line numbers.

   * What led up to the situation?
I opened LaTeXila, which had 4 files open when closed the last time.

   * What exactly did you do (or not do) that was effective (or ineffective)?
Ineffective: I reopened LaTeXila.
Effective: I added a curly brace (”}“) to the lower (not-so-high) lines and this seems to solve/workaround the issue. It looks like some characters are higher (need more vertical space) than others, esp. the line break.

   * What was the outcome of this action?
The line numbers' positions still depend on the file I open.

   * What outcome did you expect instead?
Maybe that the line numbers' and lines' positions are file independant (no line is broader/logner than the window is wide).
