Kind of reproducible on all platforms, but best on Windows here..
Open some bigger file (longer than the editor widget can hold at once), try to scroll down to the bottom.
I usually can't see the last line, sometimes it's the last two or more ( ? ) lines.
Having the find toolbar open felt kind of related, but even when having it closed it seems to be reproducible.
Using Cursor Dwn / mouse scrolling seems to make no real difference.
Ctrl+End also seems not work as expected.
