PS opens images in window way too large

Hello All,

I'm experiencing this for the last litle while.

I open images from Bridge in PS ... the first two open as normal "Normal View" (with frame/window) ... the third one opens with a window much too large.

Zooming will only resize the image - not the frame. I can only reduce the window frame to the appropriate size of the image by going through the three view options and is then normal. (hitting F 3x)

Preferences are set to UI 100% ... I tried Auto and other things ... to no avail.

Strangely it only happens by app. the third image I open, while other images are already open.

(in the screen shot they are hidden behing the huge window)

I have the latest updates of PS and Windows

The images I experience this with are about 100 -200 MB, PSD, 16 bit

System: Windows 10 PRO, 64 bit, 32 GB RAM, Nvidia 2060, Intel i9 

Thanks
