In the attached image, you can see that the syntax highlighting for the @param tag has shifted off a number of chaacters. I noticed that the syntax highlighting was still processing when I started typing, and as I typed the line above, it moved forward. It appears that it was trying to track a number of characters inserted before this point, recalculating the correct location for syntax highlighting as it went. It is difficult to reproduce. I have only seen it this once.
