I have a very strange problem. Every so often a strange window will appear on the screen - well, I say "appear", but it can't be seen. I know it's there though. It creates a sort of 'dead zone' on the screen - always in the same place.
xwininfo: Window id: 0xe1ce72 (has no name) Absolute upper-left X: 438 Absolute upper-left Y: 299 Relative upper-left X: 438 Relative upper-left Y: 299 Width: 502 Height: 222 Depth: 0 Visual: 0x21 Visual Class: TrueColor Border width: 0 Class: InputOnly Colormap: 0x0 (not installed) Bit Gravity State: ForgetGravity Window Gravity State: NorthWestGravity Backing Store State: NotUseful Save Under State: no Map State: IsViewable Override Redirect State: yes Corners: +438+299 -426+299 -426-247 +438-247 -geometry 502x222+438+299
I can't identify what process has created it, and I can't get rid of it without logging out (xkill does nothing).
Any ideas for how I can find out what is opening the window? Has anyone else come across this happening?

I am looking at the /usr/lib/unity/unity-panel-service process - I killed it, the process auto-restarted, and the window seems to have vanished. I will try it again next time it appears.
