there's a solution posted for this, maybe it can help you.

Hello Adobe,

I would like to report a BUG issue from your recent new 22.5 Photoshop update. I just updated to the newest photoshop update and now I am having this strange pixelated boarder that will not go away. It is very distracting and can be very glitchy. At first I thought it was storage issue or even a graphics card issue, looked into it on my MacBook Pro no problems with storage, I did trouble shooting, also uninstalled and reinstalled the program and I still have the same issue. Can you please look into this problem Thank you.

@JeffreyTranberry I already went back to the older version, but thanks. I may update again and give it a try.

It worked!!!! Yeaeee! Thanks @JeffreyTranberry you da best! I hope this helps *jfosterdesigns410 too.

Thanks a lot!

Anabel

Try this: Deactivate Native Canvas under Preferences > Tech Preview.

Restart Photoshop.

Updating to Big Sur should also fix this. (It has updated drivers that 10.15 won't get)

Thx guys! Very nice to know I am not alone in this frustrating issue!

Jeffrey - I tried to restore preferences as you suggested but still having same issue so, I am trying to copy-paste my system info but it doesn't allow more than 30000 characters. Could you please let me know which part of the system info do you need so I can juts copy-paste that segment and not the whole thing?

Thanks again!

Anabel

I'm not able to repro.

If you restore your preferences using this manual method does it work correctly?

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

If not, it may help if we could see your Photoshop System Info. Launch Photoshop, and select Help >System Info...and copy/paste the text in a reply.

Also, current workaround for me was to revert to former version of Photoshop.
