I have a really simple problem I can't resolve in Gnome. Every time I minimize/maximize a window, I get a series of black borderlines taking over my screen that follows the window as it increases of decreases in size. I'm pretty sure I saw this before in another distro in KDE and could turn it off in the Control Panel. However, I can't find the setting for this in Fedora>Gnome. Trust me, I've bloody tried. Sorry for such a silly, basic question. Thanks, Rory
