Horizontal pixel lines in Yosemite

I just upgraded to Yosemite. Everything looked great yesterday and for most of today, but then I started noticing black horizontal lines across the display. These lines appear every two pixels. I never noticed this before upgrading to Yosemite. These appear system wide, including on the desktop image (the default image of a mountain range), although it is only obvious on the orange sky, not the mountain range itself.

I think it may also be something to do with multiple monitors. My current setting for my Built-in Retina Display is "Best for display", but I can still see it if I choose the highest graphics resolution. My color profile is "Color LCD", is this the default? Perhaps its how the system does shading?

Restarting the computer or restarting in safe mode does nothing. Same with disconnecting the display and restarting. I don't have this effect on an external monitor either. Is there anything else that I can do?

My system details are as follows:

OS X Yosemite, Version 10.10

MacBook Pro (Retina, 15-inch, Late 2013)

Graphics: Intel Iris Pro 1526 MB

MacBook Pro with Retina display, OS X Yosemite (10.10), Retina, 15-inch, Late 2013

Go to:

System Preferences-Display

Play around with the different colors.

If that doesn't work, reboot your mac and see if it is better.

Hope this helped! 🙂

Same here but upgrade from developer preview, not a clean install. I thought it's a HW issue but now I suspect it's caused by the FW update during the install. I mean the FW might have this bug.

Specs:

MacBook Pro (Retina, 15-inch, Late 2013)

2,3 GHz Intel Core i7

16 GB 1600 MHz DDR3

NVIDIA GeForce GT 750M 2048 MB

~$ ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r | strings -6

Hmm, the problem went away on its own. I really don't know how that happened.

Did you reboot, or just while you used your mac? Or after opening the lid? Any clue?

Thank god I'm not the only one, I thought I was going crazy! I have the same issue, only worse is that on my old 2009 iMac those lines get burnt-in to the screen! Did you ever fix this? What's causing this? I've never had this issue before Yosemite.

Thanks and best

Sebastian

edit: Here's my original post I created when I noticed the odd behavior.

Guys anyone solved this problem. My less then 3 months 2014 retina macbook pro has this issue which official mac dealers in my country refuses to acknowledge. This lines are visible specially under blue and orange colors.
