Q: Transparency problem, display is mixed with video memory

I have a weird problem. First i want to mention that my transparency is off at Accessibility/Reduce Transparency settings.

I noticed that in the application background on the front is visible another application slightly what is not even on the screen. For example i photographed this:

It is very slight but on some condition the visibility is even higher. I photoshopped to see even better:

What is visible, is the whatsapp application, what is I think was minimized at least. It somehow the video memory is mixed with the rendered display.

Can somebody tell me what is this? It is possible to disable? Im editing photos/videos and it's annoying sometimes when you work with the details.

MacBook Pro (13-inch Late 2011), OS X El Capitan (10.11.6)

    Hello nendre,

     

    Thank you for being part of the Apple Community!

     

    It is my understanding you are experiencing seeing other apps thru the app you are currently working on.  I can imagine that would be distracting.  Here is a solution I hope will solve the issue for you.

     

    The first thing I would do is backup everything that is on the computer. Nothing I am going to suggest should cause any data loss, but it is always a good idea to have a backup.  Your computer has software on it called Time Machine.  It is fantastic software for backing up your computer.  Information on how to use Time Machine is available here:

    Use Time Machine to back up or restore your Mac.

     

    Video information is stored in what is called NVRAM.  I would suggest resetting the NVRAM and see if this solves the problem.

     

    Resetting NVRAM

    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. 
    Turn on your Mac.
    Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
    Hold these keys until the computer restarts and you hear the startup sound for a second time.
    Release the keys.
    After resetting NVRAM, you may need to reconfigure settings for speaker volume, screen resolution, startup disk selection, and time zone information.

     

    Have a great day!

    that is not quite correct.

    The correct information (probably in more detail than you care about):

    Parameters that have a major impact on many aspects of Mac operation (including display operation) are stored in the battery-backed Non-Volatile RAM (NVRAM).

     

    The actual display data are stored either in separate Video RAM (VRAM) or in a section of shared main RAM, depending on exactly which computer you are using and which display is in use.
