Game crash during the gui wizard

[Wide-Cat]

Describe the bug
The game crashed directly after I changed the border offset value while in the gui wizard

To Reproduce
Steps to reproduce the behavior:

1. Get a new installation of KAMI or something so you can go through the gui wizard
2. Click through everything until you get to the screen giving you the option to change the border offset value
3. Edit said value
4. See error

Expected behavior
Game would not crash, and instead the distance of the HUD elements from the edge of the screen would change

Operating system is Windows 10, 64 bit
Java version is Java 8, specifically 1.8.0_271

Unfortunately imgui's text editing fields are quite crash-y. Dragging the slider instead of editing is a temporary workaround.
