I can't figure out what's causing this, but everything on my screen has speed lines - like they're all moving to the left really fast.
I'm using the fglrx driver, that could well be the reason - it's caused me enough trouble that I'm willing to blame anything and everything on it. I'm also using a fairly old CRT, could this be one sign that's it's finally giving up?
I don't know. Does anyone know what would cause this?
