Noticed something strange about vlc, running on Lubuntu 18.04, which I think is due to LXDE. Everything I open vlc, I notice that the window has move a little more towards left than it had last-time, and the window decoration s.a. titlebar is not visible, so effectively I can no longer move, close the window, unless I can go to File > Exit/Quit -- but after several opens the window would have shifted to the left so much, that even the File menu is no longer visible. Only thing I can do at this point is to either fire-up xkill from a terminal window and kill the vlc window or restart the computer.
Wonder if anyone can shed some light on this behaviour and how to fix/get-around it ?
