Graphics Problem?

[triscuitbiscuit]

I recently got a riMac.
I was on YouTube today and looking at their logo and it looked odd like what I have in the attachment. On my Macbook Pro, it looks normal.
Any idea what could possibly be causing this? I've restarted the machine and everything is up to date!

have you tried downloading a different browser? [Chrome, Firefox, Opera] and seeing if you get the same results on those?

Maybe empty a cache or something. I've noticed that with some web sites loading the better graphics occasionally doesn't work. You'll be noticing that some pages have retina aware graphics, some not. So probably yours got stuck somewhere in no man's land.
