I used chrome Remote Desktop to access my iMac earlier today, when I got home I noticed there are about 4 flickering lines at the top right.... what gives?? did chrome Remote Desktop ruin my iMac screen?! any ideas what's wrong or how to fix it?

iMac (Retina 5K, 27-inch, Late 2015)
thanks

Horizontal lines? Vertical lines? Do the lines extend from edge to edge?
Do the lines disappear after a restart?

Picture?

Horizontal, about half the screen, lines still appear and flicker after shutdown and restart.

Maybe image retention. How long is it like this?

Since I've been back for like 30min-1hr at least... but I used the Remote Desktop like 4ish hours ago so potentially longer. It has gotten much less vibrant/noticeable since I first noticed it but its still there if I turn my brightness up

Try to wait for a little bit longer, I'd say. I had something similar happen to me before, it needed entire day to clear up.

ah, thanks. Hope it will clear up. Will never be using chrome Remote Desktop again that's for sure.

Apple does have a solution for Image Persistence issues.

Here is a link detailing it from Apple.

I use Chrome Remote Desktop everyday on both my iMac 2012 and various PCs without any signs of Image Persistence. Guess it is just hit or miss sometimes.

If image retention, that should go away completely with power off for 24 to 48 hours.
I think the Remote Desktop thing is a red herring (probably just a coincidence) --- unless you had an image like that, in that area of the screen while using the remote desktop. Might be a plan to test that, when you have an opportunity to view the physical screen while remote desktop is in operation.
