Contrast Issues due minimizing screen

Dear Rust Community,

Since the last update I’ve been observing a slight bug.
I’m not sure if it’s just a simple built-in (which you’re able to set back with a keyboard shortcut) or it’s a crept in bug while progging?
Every time I pop the game up again (after minimizing) the screen turns out to be much darker than before and I’m doing very hard to get through the game.
This issue wasn’t before the new update.
Hopefully there will be a explainable answer behind this.
Overall, I wish the rust developers much success & support! You did very well till now.

+1 here. FWIW I’m using an Nvidia 760 with latest NVidia drivers.
