Fullscreen not working in multi-monitor-setup on linux

[trimethylpentan]

The game always launches in windowed mode, if you have multiple monitors but launch the game on just one since 1.36. It seems the game recognizes both of them as one large monitor.

Game-Version: 1.36.2.55

OS: Ubuntu 18.04.3

Reproducable: Always

I have this exact same issue (and have had for quite some time now). Whenever I start the game when I have 2 monitors side-by-side I cannot enter fullscreen mode, but if I disable one monitor or mirror both monitors then fullscreen works.

I am testing on a laptop with a TV hooked up via HDMI. I have tested with and without peripherals.
