### Description of the bug

On the smaller zoom setting, tactical maps are very compressed making them unreadable. They are much smaller than they were on 515.

This is 516


This is 515


This is on every map I've played so far, this is Hybrisa for example.


### What's the difference with what should have happened?

The tactical map itself shouldn't be so compressed, and the window shouldn't also be so enlarged.

### How do we reproduce this bug?

1. Enable smaller zoom setting
2. Open up your tactical map
3. Notice the compressed size

### Issue Bingo

- [x] Issue could be reproduced at least once
- [x] Issue happened in a recent (less than 7 days ago) round
- [x] Couldn't find an existing issue about this (https://github.com/cmss13-devs/cmss13/issues)

Reproduce the issue by enabling the smaller zoom setting and opening the tactical map, then compare its size and readability with the supplied 515 and 516 screenshots. Check the behavior across multiple maps, including Hybrisa. Done means the tactical map is no longer compressed and the window is not unnecessarily enlarged.
