Key still in use after exit #82

i used xclicker with the default hotkey of "f8"

and after i closed it i am no longer able to use the f8 key

everytime i press f8 the current window lose the focus while i press f8, no other window has the focus and when i release the f8 key everythink is normal again ... until i use f8 again

this behavior still remains after restart, even i dont run xclicker again after the boot process

i am using Kubuntu 22.04 LTS without wayland (just the good old X-server)
