P: Create new window not reflecting right dimensions from clipboard

No, it's not. There's no way that would be an issue with 2 different laptops on 2 different OS's, including the one I'm using now which is only 3 weeks old. This also doesn't happen on any other program, not even other Adobe software.

@mattl63375823 Then that has nothing to do with Photoshop and is a system/OS issue.

Let me add one more oddity to this whole thing. I said earlier that even when the file>new process uses the clipboard size as the dimensions correctly that it's still 50/50 that it will paste in the correct picture, right? Often times, it pastes in the image I copied 2 images ago rather than what I just copied. So when that happens, I will X that file out to close it, then file>new and then paste and the correct image appears. But the odd part is that it's not like I went back to the internet file and re-copied it. Nope, it pastes the correct image on the second attempt despite pasting the image before that on first attempt and never going back to re-copy the image it didn't paste. It's like it has 2 images in its memory and when I want to paste image 2 only, it will paste image 1 and then 2.

Previous laptop was Windows 10, this one is Windows 11. Have not reset preferences. No time for that right now since it's not a guaranteed solution and will create more time-consuming problems restoring everything back to my needs if it's not the right thing to do. Rest of laptop specs here:

Windows 10, 11? macOS Ventura, Monterey? Did you try the Preferences reset?

This is a brand new laptop with supermax capabilities - maybe only a few weeks old - but it was happening on my old laptop too.

Okay. That is strange. I can't duplicate it (Windows 10, Photoshop 24.0.1 Release). I tried with a variety of sizes, pasting into new and existing documents, and the clipboard always retains the right dimensions. What are your system specs? Try restoring your Preferences using this manual method: https://helpx.adobe.com/photoshop/using/preferences.html#Manually. Then, go back and check the same box and try to copy and paste again. If that doesn't make any difference, quit Photoshop and put the Settings folder back.

Yes it was already checked. PS: It seems to have the most difficulty when the picture sizes I'm copying vary. In other words, I copy/paste a picture that is horizontal, then the next one is the exact same size = higher success rate of copy/paste clipboard working. But when the images I'm copying vary in vertical/horizontal format and size in general, that's when the problem always occurs.

@mattl63375823 Do you have the Use Legacy “New Document” Interface box checked in Preferences? If so, and you still aren't able to copy and paste with same dimensions, please let us know.

The update has not fixed this bug. It still happens. Again, I copy a picture from the internet by right click>copy. Then I go to photoshop>file>new with clipboard set as the doc type. This window also displays the doc size it thinks you want, but it's always wrong. The only fix is to say OK to the incorrect dimensions and repeat the file>new process so that the second coming will have the correct dimensions. And even then it's 50/50 that it will paste the last picture I copied. The other half it still pastes the image from the previous copy/paste. I've been using Photoshop for 25 years, so I'm quite sure I know how to copy/paste.
