I right-clicked on something in chromium with relatively low memory. Chromium opened up some opaque right-click boxes and never filled them in and won't kill them. These are now covering part of all of my virtual desktops. (not virtual console though)
I got information on them with
xwininfo. Here's an example from each:
$ xprop WM_HINTS(WM_HINTS): Client accepts input or input focus: True Initial state is Normal State. window id # of group leader: 0x7600001 _NET_WM_SYNC_REQUEST_COUNTER(CARDINAL) = 125152843 _NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_POPUP_MENU _NET_WM_USER_TIME(CARDINAL) = 3142781307 _NET_WM_USER_TIME_WINDOW(WINDOW): window id # 0x775aca9 WM_CLIENT_LEADER(WINDOW): window id # 0x7600001 _NET_WM_PID(CARDINAL) = 23912 WM_LOCALE_NAME(STRING) = "en_US.UTF-8" WM_CLIENT_MACHINE(STRING) = "scheherezade" WM_NORMAL_HINTS(WM_SIZE_HINTS): program specified location: 0, 0 program specified minimum size: 247 by 140 program specified maximum size: 247 by 140 window gravity: NorthWest WM_PROTOCOLS(ATOM): protocols WM_DELETE_WINDOW, WM_TAKE_FOCUS, _NET_WM_PING, _NET_WM_SYNC_REQUEST WM_CLASS(STRING) = "chromium-browser", "Chromium-browser" WM_ICON_NAME(STRING) = "Chromium" _NET_WM_ICON_NAME(UTF8_STRING) = "Chromium" WM_NAME(STRING) = "Chromium" _NET_WM_NAME(UTF8_STRING) = "Chromium"

xkill doesn't clear the zombie dialogs away. Neither does
killall xdg-open. There are some defunct Chromium processes in
ps -u $USER -o comm. Someone suggested killing
X but I want to keep all my tabs open.
This is Ubuntu 12.04, Awesome Window Manager, no compositing.
