Hi all, I have a weird issue with a brand new 11-inch 2015 MacBook Air. Since the installation and all throughout the upgrade to the latest version of Yosemite, I'm seeing weird glitches all throughout the screen. First I thought it was a hardware problem with the display, but later noticed that the screenshots are able to capture what I'm seeing. So I'm assuming it's in the rendering (software glitch)? I hate having to go back to the seller with product issues (and I should tell you I don't have any Apple stores here, so it's via a reseller). I was wondering if it's a known software glitch and if something can be done to fix this (as it may not be hardware issue?). Here are the screenshots that I was able to capture. The problem is, these glitches do not appear all the time. That's another annoying thing as you never know if the problem will show itself when it's being demonstrated to the seller. Thank you for any help you can offer me.
