I installed Hardy on one of my desktops today and it's giving me a bit of a video issue. I've got horizontal lines that are constantly scrolling rapidly down the screen. If there's a big spot of one colour they're hard to notice, but when they pass along contrasting areas, say at the edge of a window they're really noticeable. I've tried adjusting the refresh rate on the monitor, an HP w19e 19" widescreen LCD. I've also tried using the nvidia restricted drivers and tried not using them. The motherboard has a built-in nvidia GeForce 6150SE nForce 430.
