Interface choppy problem

Hi

I have little interface problem. More in this link (youtube):


<object width="480" height="385"><param name="movie" value="//www.youtube.com/v/GPqSonfmCOM&hl=cs_CZ&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="//www.youtube.com/v/GPqSonfmCOM&hl=cs_CZ&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>


Can I fix it? I have lates graphic driver (my GPU is nvidia 1800fx), dirextX 9.0c etc.

Thanks
