rMBP screen flicker

So I've had my rMBP for about a week now, and I've noticed that my screen would flicker whenever I am downloading something. It would flicker for about a second every 30 seconds or so. It stops when nothing is downloading, but it is getting pretty annoying and I'm wondering if I should call Apple up and ask for a replacement. Is anybody else having a similar problem?

----------

OK so I am running Skype for the first time on my rMBP and I am also getting the flickering. I guess it happens when I have multiple programs running.

 

I noticed the flickering earlier in the day when I was downloading something on uTorrent. I noticed it again while I was downloading Skype on Google Chrome. Then it happened again (once) while I was running Skype.

I'm not having problems waking up from sleep mode. My screen seems to flicker while I am using my rMBP.

 

OK so here is what it looks like:

This is Google Chrome with uTorrent running. This is just one of the ways I get the screen flicker. It also happens when I do other things (such as downloading a file on the internet or playing a video file). What do you guys think? I have about a week left of my 14-day return window. Should I wait for ML or call and ask for a replacement?

 

Can anybody give me any advice? I'd like the make the call right away if I need to.

 

I talked with technical support and we did some troubleshooting. I had to turn off the computer and hold down certain keys for a reset. I don't know if it'll help, but I'll also stop using Chrome. I guess I'll test is out tonight and call again if the problem continues.

BTW, I asked about their 14-day return policy and she acted clueless, telling me that they don't allow returns. I'm in Japan talking to their English support line, but please tell me that this is just a bunch of baloney? I think its ridiculous if Apple won't honor their 14-day no hassle return policy outside of the US.
