Q: EL Capitan: Screen flickering uncontrollably and forces me to reboot

I downloaded and installed El Capitan on my Macbook Pro 13-in, Mid 2012 about a week ago. I have always used multiple desktops and a second monitor to keep my apps separated and to help my productivity stay high. A day or two after upgrading to El Capitan, I noticed that the screen would flicker like crazy and I would be forced to shut down. This usually happened while I was utilizing my second monitor. I decided to reinstall the OS X and I stopped using my second monitor. Even after reinstalling and only using multiple desktops, I have the same issue recur over and over again. The Apps I commonly use when the flickering starts are: Firefox, Logos 6 (Bible software), and Scrivener. Sometimes I also have Evernote, Microsoft Word and Excel 2011 open. But the first three are always open due to the fact that I am writing a book. I never had the flickering issue with Yosemite, Mavericks, etc. Just El Capitan. I want to revert back to Yosemite but I did not have Time Machine running (I know, just stupid). So I feel like I'm stuck with El Capitan.

 

Is there anything I can do to stop the flickering? Or do I need to wait for Apple to send out an update?

MacBook Pro (13-inch Mid 2012), OS X El Capitan (10.11)

    Turned out in my case the culprit was the recently added Apple System Integrity Protection. It blocks out many scripts including Netbeans and other Java stuff. Firefox looks like to be affected too.

    If you use Java JDK or another script affected you need to turn it off like this:

     

    Reboot with "Command + R" pressed

    In the System Recovery menu enter Terminal and type:

    csrutil disable; reboot

     

    After the reboot it is done.

     

    It worked for me and the system looks much more stable and fast now.

    Nope, it came back and the problem was further down the road. I finally discovered this page and my macbook pro is included in this video recall.

    I have this problem on a newly purchased 13 in MBP, and the upper left corner flickering only occurs when I had youtube active, and in Firefox. I'm still using Yosemite. I disabled the hardware acceleration, but the fix did not last.

    Restart computer while holding down Command R. Using First Aid, repair and re-repair Disk and Disk Permissions until nothing else repairs.

    Every time it flickers I see this line in the log:

    I found it was Google Chrome browser for me too that was causing flicker in my Macbook Pro Retina 13 Mid 2014, tho it could be Shockwave or something else Chrome is running.  Started in early 2016, and happens every few weeks.  I just quit Chrome and start it again.  I'm now trying turning off hardware acceleration.  I also find Chrome makes my CPU temp go up for no reason.

    I have a 2008 mac pro  i have followed all directions but still to no avail.

    heres what happens. I turn on power the screen comes up and the chime and progress bar gets half way and screen glitches and go into reboot when it comes back wit " reboot with space bar or wait" i wait a few seconds and i am at my home screen. i get a kernel panic info tag and that the end. now the only thing i have add is new memory (which is another problem) new samsung 250 gig ssd, and new video card for more cuda cores for my FCP X work and after effects.. what else can i do to troubleshoot this issue. Any ideas.
