Hi are these PNG images, if so uncheck these options as a temp fix, restart Photoshop, hopefully Adobe will have a fix soon
YES! Thank you so much, Ged! That worked. I hadn't noticed the fact that all the files were .pngs.
This problem should be fixed after the Photoshop 19.1.2 update. You can install this update via Creative Cloud desktop app.
Also, you can refer the list of the fixed issues after the Photoshop 19.1.2 update, here: Fixed issues in Adobe Photoshop CC
Glad to see this is getting fixed. It's really annoying!
Does anyone know how to make this happen?? I have had it happen before & exploited it for a project, but once it was fixed, I couldn’t make it happen again
We're really sorry for the trouble. Could you please let us know the exact version of Photoshop you are using now? The above issue got fixed in Photoshop 19.1.2 update release.
