Introversion

I'm using two monitors in Linux Mint 17.3. Upon launching the game in fullscreen, Uplink takes over both monitors, which I don't mind, even if it only duplicates the screen. Upon exiting my game, the desktop on both monitors was shared and corrupted. Linux isn't properly taking a screenshot of both monitors, only one of them, so I took a picture of the issue with my phone:

When my screensaver comes up, the issue persists:

I'm new to Linux, so I'm not quite sure what commands I can use to give any specs for my machine that might be useful.
