When I launch the game the screen immediately goes black although the music is audible. If I alt tab out and back again, visibility briefly returns before going black again. If the game is put into windowed mode, a change occurs. Instead of being black constantly, the screen now blacks out every second or so but this continues after the game is closed and then the screen blacked out for good and I had to restart.

EDIT: It seems that Radeon Overlay was the culprit. Disabling it fixed the issue.
