Undocked document window resizes when switching between tabs in PS 2023

[adamc82922445]

Photoshop 2023 is resizing undocked document windows when you switch between tabs on that window. This is infuriating because when you are using undocked windows, you often have other things open on the screen that you dont want obstructed. Additionally, it doesnt remember the window size when you go back to a tab that you previously resized. So if you are going between tabs frequently, you have to constantly resize the undocked window. Its ridiculous.

1. Undock a photoshop document.
2. Add multiple other open documents to the undocked window so that you have a few tabs
3. Switch between the tabs and watch the window size change

Expected result: Window size should remain whatever size you resize it to (this is the behavior in every version I have used before 2023)

Actual Result:  Photoshop resizes it to fit the size of the document open on whatever tab you click on

I'm not sure that's what causes the problem, but can you check those options shown on my screenshot?
(window>arrange)

(all the match options)

sometimes they get activated/deactivated if you update...

did you no reproduce the problem described in my issue?

[Imaginerie]

Not right now, but it did happen to me in the past. That's why I said I wasn't sure it would solve a problem, just offering a possible remedy.
Hope it helps!

That helped me, thanks! It still resizes a teeny bit, but so much better than before. If I open a new file after doing this, it still does resize that particular tab, but the others will remain the size that I resized it to.

Glad it helped!

Same: I hate it. switching between tabs is a pain. Opening a new tab with a smal image completely resizes the window... This must be a bug right?

Same here. Whenever switching from another app to Photoshop, the window gets resized beyond the bounds of my viewport. Same thing happens whenever I zoom.

I tried:

- Window > Application Frame toggle
- Window > Arrange > Match All
- Preferences > Tools > Turn off Zoom Resizes Windows

Nothing works. Very annoying bug!

Only thing that worked is to manually size the window using the mouse and window handlebars. Then this gets remembered as the default window position and size.

Hi there,
This was driving me nuts after a reinstall of photoshop 2024 as 2025 which was not working well with lightroom.
THE SOLUTION IS.

CHOOSE TILE WINDOWS WHEN USING TABS
PROBLEM 100% FIXED.
