I believed this option is enabled by default. I use Fedora + xfce for years by now, and didn't touch that part of configuration for long time, so I'm not sure if that is enabled by default, well in Fedora. But I installed completely new xfce desktop environment in Ubuntu two days ago, and remember clearly that I didn't configure that part, then I install cairo-dock and enable the default-panel theme, and the problem came out.

If I kill cairo-dock process, this problem will be gone. I don't know how to exactly describe my theme problems, please look at the bottom and top parts of the screen in my screentshot, there are lines or frames in the screen. They don't affect my use, they are just there, like part of the wallpaper, quite annoying. They are created by cairo-dock themes . Only one line or frame (the bottom one) will be created by themes such as Default-Single, two lines or frames will be created by themes such as Default-Panel. FYI: cairo-dock v3.4.0 Fedora 21 32-bit Xfce v4.12 To manage notifications about this bug go to: https://bugs.launchpad.net/cairo-dock-core/+bug/1430289/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~cairo-dock-team Post to : cairo-dock-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~cairo-dock-team More help : https://help.launchpad.net/ListHelp
