graphics sprite problem. please help..

hello

i have graphics problem

The problem is that its a platformer side scroller game.

and there is a door in the scene.

When the character walks to the left or right. the graphics of that door , the colors vibrates or moves a little.

and it happens to not only door but sometimes many other objects too. like a wall painting, table , chairs. etc..

please help..

Sounds like a Driver related problem,....Try updating all of your display drivers and get the latest version of your browser.

i friend told me its a linear filtering or something like that. i dont know how to fix it..
