Just updated Photoshop and now have problems pasting something into a new layer

[DigitalChickster]

I'm having the weirdest thing happen. I just updated to Photoshop 12.2.0 today. And now... when I have a photoshop file... I tried to drag a logo from another layered PS file I have.... and it does move to the new file on a new layer... but it also pastes that same image onto the original bottom layer. I tried doing a copy/paste... same thing. This is so weird! I'm guessing it has something to do with the update? Has anyone else experienced this? I am on an iMac. 

Update: I had a layer mask on that original bottom layer... and once I deleted that, the weird pasted logo went away. So it's something to do with the layer mask.

Hello: I just note the same problem with the layer. When I place a new layer you can not see any action (curves, pencil, brush, eraser). it is annoying. I found a convenient quick step, jut turn. on and off the view for the background and you will see your normal layer. I repeat this is a quick solution, NOT a real solution. It goes to go to Adobe gurus, to have it fixed!

Thanks, NYTaxista! At least I know I'm not the only one experienceing it! Thanks for the quick fix... I'll use that until it's fixed for real!

I am grateful for your help, but I don't think this should be marked as fixed. You've given me a work-around, but this issue really needs to be looked at! I just tried to do a simple graphic I've done a million times before... and it took me twice as long because of this glitch! I don't know how to unmark the "correct answer" designation, but I think we should undo it so that perhaps someone else will find a fix?

This was driving me crazy, but I just figured out what to do. 

I found it here: https://helpx.adobe.com/photoshop/kb/known-issues.html

You need to go to Preferences > Performance and UNCHECK "Legacy Compositing." That worked!
