Burn in on December 2012 iMac (27")

I have a December 2012 27" iMac with all of the upgrades to CPU and 3TB fusion drive. I swapped out the default 8GB ram with what was supposed to be compatible ram from Crucial. I am mentioning this in case it might make a difference in the problem below.

I have noticed a burn-in-like effect randomly on my screen. It seems to be most noticeable when I've been using the Mac for a little while, and I click the Applications folder in my dock, and the tile view appears with the dark grey background. On this background, when the problem is happening, you can see vertical stripes going across the grey area.

I haven't discovered the pattern of when it appears and goes away, but it seems like it appears after the computer is being used for a little while, and goes away if I stop using it for a while.

It doesn't behave like normal burn-in, so I'm thinking it could be: a software bug, or the video card, or the non-standard ram, or perhaps another issue related to the thin design? I can't tell if the striping is only happening in dark areas, or if it's just only visible in those areas, when it happens.

Anyone else seeing this?

I took a picture:

Hey nice Bokeh 😉

I have a late 2012 and it had a hint of IR during the first month, 1 time. Since then, I have seen it 1 or 2 times. My iMac runs 24/7 365 and I have only seen it a few random times since then. I got mine in Jan 2013 I think. I got Apple care and if it happens again, I have a case with Apple so I can get it replaced.

I think you should determine if it's a serious consistant problem or was just a random anomoly ... if it happened 1 time ... forget it. If it happens everytime you use it... then go for a repair.

Hey!

I've had the same problem (image persistence) on my iMac 27'' (late 2013).

I had to have my panel changed through Apple Care a few days ago. The thing took 30 minutes.

Apparently they solved the problem on later models.

If your iMac is still guaranteed I would strongly suggest that you have it serviced (whether you have Apple Care or not). It is not a software problem that you can solve using the white screensaver!

It is a hardware problem.

Hope this helps!
