JPEG green in Preview.app on OS X 10.11

Hello everyone, that my first message here, i'm using a Mac almost 8 years and never has a problems that i can't solve by myself, but this time i tried everything and don't know what else to do.

I have a Mac Mini late 2014 (8Gb RAM, Intel HD 5100) with OS X 10.11, the problem is when i open JPEG photos(not every JPEG, more detailed i'll explain below) in a Preview.app the screen of Preview.app turns green like you can see in a screenshot below, some it times also crashes, i'll leave the crash report at end of a message

Does anyone have same Mac Mini with the OS X 10.11? i want to know if that is software bug or it's a hardware problem? any ideas what that can be?

Here a list what i have tried

I have installed twice clean OS X, that did not helped.
Checked with Apple Diagnostics and it nothing found.
Checked RAM with Memtest86 i did 3 passes that took almost 5 hours, no errors found.
If i "save as..." the JPEG that turns green in to PNG or TIFF then it opens normally, after saving it back to JPEG again it turns green...
As i said in beginning not every JPEG turns green, example any photos 15MP from my Canon 500D they all green, but photos from iPhone 4S they open normally, after that i tried to resize a photo from Canon 500D to 40%, after resize they shown normally, then i tried to resize iPhone photo to 300%, i expected that it will turn green after resize, but strange it still open normally, also a panorama photo from iPhone are green...
In a Safari.app every photo opens normally.
In a Safe Mode they also open normally.(maybe the problem is in rendering?)

Here if anyone want to try i compressed and uploaded 2 photos, one from Canon camera and one from iPhone(link)

Here is the the crash report of Preview.app (link)

Thank you

Alex.

Unfortunately, the problem is not at all solved for me. True, when zooming in and out the image I can find some sizes where the green cover disappears totally or remains on a part only of the screen, but this is not a solution. just a temporary work around.

I also urge Apple to consider a quick solution to this bug.

Why very difficult some easy things on MacOS about photo or files ??

exactly the same problem for me since El Capitan was released. Changing the preview's preference to 1 pixel image equals 1 pixel screen and back again don't resolve this issue. Same issue in quick preview from finder.

Anyone solved this?

I was advised (by apple support) to start in failsafe mode, then it works but after normal start it does not.

Second advice was to:

Here are the next steps:

1. Shut down the computer.
2. Plug in the MagSafe or USB-C power adapter to a power source and to your computer.
3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
4. Release all the keys and the power button at the same time.
5. Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step

6. Turn on your Mac.

7. Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.
Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.

8. Release the keys.

Did not help either, next advice was to reinstall.

I have not tried that yet, has anyone solved the issue by reinstalling the OS?

I have tried everything that you wrote, as i said in the first message in the safe mode it shows normally, i reinstalled the OS three times, those 8 steps that you wrote are for reset NVRAM/PRAM i also tried.

The issue is clearly bug of OS X 10.11, it's already 2 months and Apple still did not fixed it... 😠
