Comment 6 for bug 223436

I'm confused as to why "Make sure that the screen resolution can be changed even at very low screen resolutions." isn't something that can be considered a bug. Try what he says and tell me how you get back to the main resolution easily:

"Ninth Task: Change screen resolution.

This was easy from the Preferences menu under Screen Resolution, and she changed it to the smallest size available: 720×400. However, she clicked “Keep settings” straight away, and couldn’t work out how to get it back because the screen was too small to display the entire height of the Screen Resolution menu. Eventually I had to do it for her by tabbing through the options.

This is pretty ridiculous – you can’t make it shorter and you can’t move it up past the top of the screen. There’s no way I can see of being able to change the resolution using that menu when you’re on a small resoltion – without tabbing to invisible options that you don’t know are there. Maybe I’m just missing something, I’d be happy to be enlightened."
