Game keeps shaking up and down on screen

[Firewing55]

I am playing Pokemon XD Gale of Darkness but all the while I am doing so, the game screen keeps shaking full screen and wide screen even though it is at regular window size. I don't know if it has something to do with the graphics settings; I can play just fine, but its a little annoying and I need help.

This is a problem with Dolphin's automatic detection of anamorphic widescreen. You can avoid the issue by setting Graphics > General > Aspect Ratio to Force 4:3.
