In recent Nightlies I can reproduce it if I snap Nightly to a whole half of the screen. The issue is visible when I have a blinking cursor in the address bar, but not if the cursor is in about:newtab's own search bar.

Do you still see this issue? I don't see it on Windows or Linux in recent Nightlies.
