Hello, I installed Fed 13 on a laptop with Intel Core I5-430M CPU and integrated Intel HD graphics Media Accelerator. Everything works perfectly except for a 'trembling' (vibrating?) screen. It seems to be slightly more pronounced when running on battery. This is irritating and tiring after a couple of hours. Anybody else experience this on laptops with Intel Core I3/I5/I7 CPU's using Intel HD graphics. Could it be the Intel driver? If I am the only one seeing this should I report it as a bug?
