Well, not the screen itself, but basically, when I'm browsing on my MacBook (Snow Leopard, all updates installed, using Firefox), the display sometimes flashes black and when I put my mouse in the corned to activate the screensaver (something I've had set up for ages), it often doesn't work unless I try a few times.
This is on a clean install of OS X, and the last thing I've done to it was enable FileVault and change some firewall settings.
I'm probably just being pedantic, but is there any known problem causing this?
