    Hey there, I've been having some pretty serious glitches following the upgrade to El Capitan and was looking for some help. I'm on a MacBook Pro (13-inch Mid 2012) running 10.11.1 (2.5GHz Intel Core i5 and 8GB 1600 MHZ DDR3). Application windows have been leaving lag trails across the screen, and the whole display has been "twitchy:" scrolling makes the toolbar text appear to vibrate, and sometimes thick lines of glitch appear across the screen at random intervals. It appears while using all different applications. The entire display failed today, showing only colors and static, which I took photos of (screenshot didn't capture it correctly).

    Following the crash today, the audio card seems to have failed as well; I have no audio output from either the built in speakers nor headphones that I connect. In system preferences, no audio outputs are available.

    I screengrabbed it a few times, and also got a video, here they are.

    It really looks like a GPU issue.

    The stock version of your computer ships with 4GB of RAM. Did you upgrade it at some point? If so, can you put the original 4GB of RAM back in and see if the problem persists?

    I got it straight from Apple with the 8GB of RAM, I ordered it like that (I do a lot of video editing and music production so I wanted more than just the stock 4GB)!

    I guess you could try a clean install.

    That's definitely an option.. But I'd rather avoid having to go through the whole process of a clean install if I can; restoring everything from media to license files is a real pain haha.
