Everytime I start my computer and log in, there is a 1x1 unnamed window with a settings cog icon, at first I ignored it, but now I'm getting suspicious of this window (as in, malicious kind of suspicious).
I've tried identifying what PID it has using xdotool getwindowpid
which returns
[xproot@xproot-lappy ~]$ xdotool getwindowpid 65011715
window 65011715 has no pid associated with it.
I also tried xprop _NET_WM_PID | sed 's/_NET_WM_PID(CARDINAL) = //'
which returns
_NET_WM_PID: not found.
now both of these commands work with regular windows, yet it doesn't work with this? just adds more suspicion to me. Anyone could bring up a solution? How to find what is making this window? I originally thought it was kde-connect-indicator since it started appearing as soon I added that to startup applications but removing it from it doesn't help.
_NET_WM_PID
relies on the application setting it, which many do but not all. – Gilles 'SO- stop being evil' Jan 18 '22 at 18:50
