Hi! I just downloaded the last version of the game (Version 5.1, 07/07/2020), and when I try to open the "game-z" launcher, the game opens but its riddled with green stripes, and they don't go away. I'll share some screen shots.
I don't have this problem when simply opening the "game" launcher.
Fun fact, it's the first time I try this game, and seeing as it was called desolation, and the dude at the beginning says something about "See what you have done. Do you enjoy the world you have created?" or something like that, I totally thought the green lines where normal and thought it was quite original. Still, it was really hard to read xD
