Created attachment 4566 Screenshot attached to show what is going on. (see: bottom lefthand corner) When I resize a terminal window to the bottom ~200px or so (on a 1080p screen), the contents of the window will increase in size and mirror themselves in the bottom portion of the screen. If I continue to drag left from there, the content mirrored will push right (and vice versa). Mirrored contents will stay on screen until another window is dragged over it. Running Arch Linux + ATI Catalyst 12.6-4, though this has been happening for several Catalyst and XFCE versions now (and I'm not actually sure if this is a video driver related issue).
Not a terminal bug, but the other application not redrawing.
