Version; 22.5.1
OS: Mac Big Sur (11.5)
Reproduce: Have a non-retina external monitor connected to a Retina Macbook as the main screen. Open a file. It will open at 100% but with the window sized smaller than the image.
Expected: Files used to open with the entire image visible within the window, so you don't have to resize the window, nor click the green mazimize button.
Seems this issue was introduced after version 22.4.3; See these two discussions for further explanation / confirmation of the problem:
