Before you click the spoiler tag, read these bulletpoints first:
* This has never happened to me
* This started last night during a game of Resident Evil 5
* Thinking it was the game, I turned it off that night, then on this morning to find out it affected the dashboard too
* Doing some swapping of consoles and inputs, I found the Wii worked on the same input without the filter, so it was Xbox related and not my TV.
* I bought some new component cables, and replaced them. The problem was still there. However, after some wait, the problem went away and the dashboard was back to normal. Unfortunately, it went back to the weird filter. Then back to normal. It just jumps back and forth.
* I have not experienced any constant lockups, or any other graphical errors besides what's pictured, even prior to this happening. I played the entiretly of the Guitar Hero Metallica demo without any problems - graphical filter aside.
Now that you've read this, please click the spoiler and see if my picture matches what you have experienced, and if you think my Xbox is simply dying or I need a part replaced.
