The default font in gedit is no longer monospace
When syntax highlighting makes a word bold, it actually increases the width of that word. This didn't happen with previous versions of gedit.
This is immediately noticeable, should take a few seconds to fix, and will make many more programmers sad than happy if it is not fixed.
