Content messed up on retina iMac! Help!!!

[nyc212]

Hello. So I got my retina iMac last week on the 29th. I've been using photoshop on it and thats about it. i got the model with the m295x, ITB ssd, and the 4.0 i7. I upgraded the ram to 32gb my self which was ordered from crucial. All was going well until today where some of the websites and some of my mail had lag on the screen. This has me really worried. Ive attached screenshots/ I restarted safari and the problem went away but then it showed up again on my mail app. I haven't installed any shady software nor downloaded anything of the sort. Everything was also updated to what was available. Is anyone else having this issue? What should I do? Please help. The first three pics are of webpages and the last one is a header of an email in the mail app. Thank you.

Is that flash content?

I had issues with yesterday's YouTube logo rendering weird in Safari as well. Only in Safari on my Retina iMac. Chrome and other programs on my Retina iMac, as well as Safari on my rMBP rendered it fine. Image is at http://s.ytimg.com/yts/img/doodles/yt_yoodle_election_2014_2x-vfltSi3Ec.png
Apple needs to look into this issue, it's a strange one.

Same for me and I'm on the standard GPU and thought maybe I need to get the M295X, but the system hardly taxes the GPU.

Can you do me a favor and see if you're having problems on the iMac w/ 5K display site on Apple's website, paradoxically.

Simply scroll down and back up into the zoom picture at the top, and then back down. How does that work on your machines?

Thanks!

Perhaps it's coincidental, but I briefly saw similar artifacts on my late 2012 27" iMac the other day - I had to quit and re-launch Safari. So I wonder if this could be a Yosemite bug that's more prevalent on the retina iMac for some reason.

Thanks for letting us know. I hope you got this right.

I take it your Late-2012 has never done this under Mavericks or Mountain Lion?

My Late-2013 iMac never had any issues. Of course, eeeeeeeeveery now and then, Safari, or whatever else, will crash. However, I've been using Yosemite since beta 2 and never had any issues with Yosemite.
