Comment 17 for bug 504368

Window manager varies. In the original report it was openbox (as I believe I stated, in comment #7). Current window manager is xfwm4. For the screenshot provided, I intentionally moved the window with Alt+left_click as I knew this would trigger the issue (also indicated in comment #7). However, as stated before, the issue happens seemingly randomly on its own without moving the window or interacting with it in any way.
