I have Photoshop 22.1.1 running on a late 2015 iMac 27" (3.3GHz, 32GB RAM, AMD Radeon M395 2GB graphics) with an external Asus 1440p monitor connected via Displayport. I'm having an issue with Photoshop periodically flashing constantly between the image I'm working on and black every half second or so. From my experience so far, this happens when I am working outside of Photoshop (as I type this it's happenning sporadically). The moment I click into Photoshop, it stops. I initially thought that it was because I've only just recently acquired the 2nd screen, and that because the graphics card only has 2MB RAM, it might be struggling. However, this is only happening with Photoshop. Is this a known glitch? If it is, I'll downgrade as this has only started happening within the last couple of days, even though I've been using this version of Photoshop for a little while. Thanks in advance.

Hi,

 

We're sorry about the trouble with Photoshop. Would you mind telling us which macOS version are you working on? Have you tried disabling the option to Use Graphics Processor from Photoshop to check if the issue persists? If not, please try it by going to the Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.

 

Also, do you still experience the issue if you have the external monitor disconnected?

 

Regards,

Nikunj

Hi. I'm using Mojave 10.14.6. Will check on how it performs with Graphics Processing switched off. Having the external monitor disconnected isn't an option regarding my everyday use of the machine, so if it continues to do this, depending on whether there are any other workarounds to try or not, I might need to end up downgrading. I'll keep you updated. Thanks for your reply.

This is no longer a correct answer, as the problem has returned.
