Tomb Raider Loading Screen???

Just curious, when I load Tomb Raider it scrambles and jumps all over with flickers and flashes then comes to the main menu screen and everything is normal, is it supposed to do that or is my disc funky?

Anyone else have this with their game? It doesn't affect gamepley and never shows it self outside the main menu / load screen I just figured it is supposed to be indicative of the "storm" that  all encounter in and around the island or my disc has a glitch in the initial load screen.

Thanks.

Homer - What do you want me to do about it, I'm only (while counting his fingers slowly)... one guy.

haven't experienced any of these problems.

yes it does graphic glitch and anoying pause,when starting
