My screen is flashing green and I can't even navigate around an open jpeg on my Macbook Pro.

I have a 2019 Macbook Pro that's never had any issues before.  All of a sudden I can't even open a simple photo on PS without the screen flashing green, making it impossible to view or edit photos.  Looks like maybe a graphics issue?  I am running the latest version of PS...which I think may be the problem, as it's been working fine (with nearly daily use for years) up to this point.

Hi there,

Thanks for reaching out.

Which version of Photoshop and macOS are you using? Does this happen with only jpeg images? How do you open the image, by drag-drop or from the menu? 

Try doing it once again by disabling the GPU use. 
Go to Photoshop's Preferences > Performance, uncheck Use Graphics Processor, and restart Photoshop.

Let us know if it helps.

Thanks,

Ranjisha

If disabling the graphics processor doesn’t help then maybe try resetting Photoshop preferences?

(read this entire post before acting please)

Resetting restores Photoshop's internal preferences, which are saved when Photoshop closes.

If they become corrupt then various issues can occur.

Here’s some info on how to do that:

https://helpx.adobe.com/photoshop/using/preferences.html

Manually removing preferences files is the most complete method for restoring Photoshop to its default state:

Note re macOS: The user Library folder is hidden by default.

To access files in the hidden user Library folder, see here for how to access hidden user library files.

Unexpected behavior may indicate damaged preferences. Restoring preferences to their default settings is a good idea when trying to troubleshoot unexpected behaviors in Photoshop. check out the video

And here’s an earlier forum discussion as an aid to understanding

You may want to backup your settings and custom presets, brushes & actions before restoring Photoshop's preferences.

Here is general info about that:  https://helpx.adobe.com/photoshop/using/preferences.html#BackupPhotoshoppreferences

Before you reset your preferences

in case of future issues, I suggest you make a copy as Adobe may need one to check problematic references. 

Quit Photoshop.
Go to Photoshop's Preferences folder

Preferences file locations: https://helpx.adobe.com/photoshop/kb/preference-file-names-locations-photoshop.html\

  [on MacOS see: Users/[user name]/Library/Preferences/Adobe Photoshop [version] Settings

  Note for those on macOS: - be aware that the user Library folder is hidden by default on macOS.

  https://helpx.adobe.com/x-productkb/global/access-hidden-user-library-files.html

  In the Finder, open the “Go” menu whilst holding down the Option (Alt) key.

  Library will now appear in the list - below the current user's “home” directory. ]

Now you can drag the entire Adobe Photoshop [Version] Settings folder to the desktop or somewhere safe as a back-up of your settings.

Note for those on macOS:

Preference preservation is affected by macOS permissions,

you’ll need to allow Photoshop ‘Full Disk Access’ in your Mac OS Preferences/Security and Privacy

It may even be time to reinstall Photoshop.

It’s recommended that you use the Adobe CC cleaner tool to remove all traces first.

(See above about preserving preferences though! Its worth preserving them unless they are corrupted.)

https://helpx.adobe.com/creative-cloud/kb/cc-cleaner-tool-installation-problems.html

Uninstall Photoshop BUT make sure to choose the option “Yes, remove app preference”.

Once that process finishes, start the installation process and look into the “Advanced Options”. Uncheck “Import previous settings and preferences” and choose to “Remove old versions”.

I hope this helps
