Sometimes when I play osu in the public on my laptop, I absolutely have to avoid certain maps because people walking by might see backgrounds from those maps and think I'm weird. I'm mainly concerned about the lowered dim during breaks, because it gives enough time for my friends or whoever's around me to see the background. Trust me, I don't want to be playing +Danshi and my buddies walk behind me for a peek at what I'm doing to find...... THAT.
