if some Windows 11 user experience an black background issue

After the update, some Windows 11 platforms may experience an issue where the black background cannot be removed. This is caused by certain incompatible automatic optimizations in Windows 11. To resolve this,

1 navigate to the Steam installation directory of the game, locate the DreamGlobe.exe file,

2 right-click on it, select Properties → Compatibility → Disable full-screen optimizations. This should allow the game to run properly.
