The doc page for upgrading to 2021 LTS says that Image.scaleMode is now set to ScaleToFit by default. It recommends using -unity-background-scale-mode: scale-and-crop; to go back to the previous behavior, but that doesn’t work for images. The actual line should be --unity-image-size: scale-and-crop;.
Thanks for finding that out!
Have you reported the problem on the page? (using the “Report a problem on this page” at the bottom) This is the best thing to do as it notifies the documentation team directly.
No problem :). To be honest, I haven’t. Do you know if they really look at those reports? I’ve reported problems with that interface like 15 times and I’ve never seen any of them fixed.
EDIT
I’ve reported it just now, in case it does work this time.
