I see that something similar to my issue is an old JIRA:
Most of us tend to use our "widescreen" monitors in the "portait" position
(i.e., rotated 90 degrees), so that we can see more code vertically.
However, this means that dialogs such as the Project Settings are forced to
scroll horizontally. And in many cases, you can't even see the buttons until
you scroll. For a while, I didn't even know the buttons were there because
they were not visible! See attached image.
I'd strongly suggest that the buttons be moved out of the scrollable area so
that they're always visible.
