I've opened this question, and I noticed a strange effect on the last two words of the title:
At first I thought about a rendering glitch, but then I noticed the other marks and realized (at least I think) it's because of the page's background, which has a feature overlapping strangely with the title. It happens with all questions with long titles.
Is it supposed to behave like that? I found it distracting, especially since I didn't know what it was at first.
