hi, would you be able to share info about the computer you're using to play (os, &c.) & links to screenshots through https://ayearofsprings.crd.co/#contact? i haven't had any reports of this from anyone else & i'd like to fix the issue if i can. if any error is displayed, please share that in your message too if you don't mind.
edit: this issue has been fixed but i'm just going to note potential fixes here in case anybody else has issues!
1) check that graphic card drivers are up to date & update if necessary
2) boot the game while holding shift (or press shift+g in-game) & select a different graphics renderer
3) try toggling fullscreen by pressing "f"
