There are times on my 2015 13" rMBP, while I am surfing the net, where a website I'm wanting to look at will come up with a thin, horizontal black line running through it. Sometimes the line will l slowly fill in, while at other times, I will need to refresh the page. I've had earlier versions of the MBP (non-retina) where I have never seen this happen. Not sure what it is that's happening here. Any ideas?
 
Perhaps the website is messed up? Definitely does not sound like "a retina issue".
It's either the website you're visiting or some messed up software you might have installed.
( by "software" I understand: drivers, browser, browser plugins, other apps running in the background, etc. )
