Yes, but when I stop scrolling and scroll up even a little bit (by accident, or because I want to scroll up and read something I missed) they appear again. I think the only good UX possible is to have a button to show/hide them instead.
I'm sorry, but I disagree. The lowest interaction cost is scrolling; it's a natural, continuous, and almost involuntary gesture. Having to click or tap a button requires the user to stop, evaluate whether the title interests them, and decide to make the effort to tap. The interactions you're describing are intentional and measured. I'm sorry but if the content is truly all you care about, I recommend the previous option or activating your browser's reading mode.
