I am not sure I understand the problem so I will be asking a few questions.
When is it flashing?
As a default screensaver, it isn't flashing?
Are you also saying that if it is not in the screensaver mode, it doesn't get dark?
What is your video card and operating system?
Try to set the Vsync to Clamped by hitting the S key so you can see some status at the top of the screeen. Then hit Ctrl-V until is says VSync: Clamped.
