Screenshot of Ghost windows described above
SUMMARY
When using X11 display forwarding to run GUI apps on remote servers via the SSH
-X or SSH -Y commands, ghost windows i.e. empty window boxes with the Xorg
symbol appear in the task manager panel and while alt+tab-bing to switch
windows; these ghost windows clutter the task-manager and task-switcher making
it difficult to switch between different progras. The windows remain even after
the SSH connection is closed. The only way to get rid of these extra windows is
to restart the OS.
STEPS TO REPRODUCE
1. Login to a server via SSH from Konsole or any other terminal, with X11
display forwarding enabled
2. Launch remote GUI application from the terminal
OBSERVED RESULT
After using the application for a few minutes and opening and closing sub-menus
within the GUI application, ghost window appears in icons only task-manager and
alt-tab task switcher.
EXPECTED RESULT
No ghost windows appear, any and all windows associated with the SSH session
should go away when the SSH session is disconnected.
