Occasional crash scrolling to settings bottom

[BachoSeven]

On: last development version After a while, I could not reproduce this anymore, but I got this error a few times when scrolling to the bottom of the settings (and continuing to scroll):

Pretty sure I've also seen this bug. This bug could hide potentially anywhere, maybe even in an upstream library.

Unless someone finds a way to reproduce this reliably, I'm not going to spend any time on this, especially because I'm planning on rewriting the TUI with a different library.

But let's keep this open just to prevent duplicate reports.
