P: Create new window not reflecting right dimensions from clipboard

I'm having this same issue, though I should add that I'm still experiencing the issue after enabling Use Legacy "New Document" Interface. I also tried Sameer K's suggestion of renaming the UXP directory to ~UXP, but that didn't fix it, either.

I gather that the legacy New Document interface helped most people with this issue, but the behavior was exactly the same for me: it doesn't seem to read the current clipboard dimensions until it's already applied its stale dimensions to the new document. It seems to set the new document's dimensions to some previously cached clipboard size and then read the up-to-date clipboard size from the OS. Again, this behavior is identical between the new and legacy New Document interfaces.

I'm also on Windows 10 (specifically Windows 10 Pro, version 10.0.19043), and I see this bug on Photoshop 23.4.1 Release.

I just want to add another vote to fixing the issue quickly.  I prefer the new interface, but will use the legacy interface as the issue had been a serious hinderance to my workflow.  I'll probably forget this and never change it back.

One more annoyance? One more update that seems to ignore users' workflows? Unless there's a new shortcut for it, when I create a new document (Cmd + N) to create a new document based on what's in the clipboard, Photoshop now starts by default with the latest dimensions used. So every time I need to do this, which can be hundreds in a day, I need to close it and redo Cmd + N, as the new dimension is rarely the same as the previous used. On the second time it uses the clipboard content. That's even worse than the "improvement" from CS, when Photoshop would promptly retain the resolution from the previous new document and automatically double one dimension when the other got doubled -- all this process of doubling the size of images for Retina displays must be done manually now, after closing and starting the new document window. Four steps more, hundreds of times a day, I think of all the extra strain that could be avoided just by going back to what CS had, which worked perfectly.

Thank you Jain, this worked for me, though I would prefer the newer visual dialogue.

There are multiple workarounds for this bug until it is fixed by Adobe.

One work around uses a script to create a new doc from the clipboard, either bypassing the GUI or using the legacy new doc GUI. This allows you to use the "new" interface for everything else except for when you need a new doc from the clipboard.

Some of the other solutions may also allow one to retain the new interface, I don't know, I haven't tested them as I always use the legacy interface anyway as I prefer the old way. The method of setting the legacy new document interface in preferences is just the quickest and easiest method to work around the issue.

See Provazi's answer above: "Just switched to Legacy "New Document" Interface and it works fine that way. Edit > Preferences > General > check Use Legacy "New Document" Interface "

Thanks complexity... lives just got saved
