Okay, I'm definitely seeing this... There are things popping up like medals for crucible in challenge, they just flash, but don't say anything. I definitely don't remember this happening before and if you're thinking about adding medals to challenge.... Please do cause that sounds awesome. But if your not. It's distracting as heck. Also in the first arena there are some serious frame rate dropping issues that might need some looking at. I realize that we have rise of iron out now, but, that's no reason that people shouldn't report bugs in older content.
