I found there is a small window floating at the corner of the screen. this window is not working properly as it always displays part of contents in other windows. I don't remember which app opens this up as the computer has been on for weeks. This window can not be closed by mod+shift +q. of course we can just leave it there but do you know if there is any way to close such stubborn window?
Thanks in advance!
try xkill, it allows to force close an x window.
@diablo465 can you use `xprop` on the window? If so, maybe you can use `xkill -id <something>` to kill it?
@BatmanAoD here is result after using xprop to that window: WM_NAME(STRING) = "[i3 con] floatingcon around 0x19cd330". the result is completely different from other windows. I can not find the pid of the window that is why it is not possible to use xkill or kill to close it.
I was able to kill such a window (remnant of something wine) with xwininfo -all to determine the process id, then killing that process and associated processes with command line C:\windows\....
Try restarting i3 (i3 restart or Mod+Shift+R I think), then killing the window using Mod+Shift+Q or xkill.
From the above post:
Use xwininfo (and click on the offending window) or use -all and find it
Then use xkill -id [window id from xwininfo]
That will do away with even the most persistent pests....

Are you sure it's actually a window and not just an artifact left by some kind of bug?
I frequently get this for Wine system tray icons. KeePass for example creates such windows, when I change monitor configuration with xrandr
@BatmanAoD It could be left by some kind of bug, as it doesn't function properly. but I wonder if there are ways to deal with these bug windows.
My point in asking was that it might not be a window at all, in which case the wm (be it i3 or anything else) might not even be aware of it. Does it remain in place when you switch to a new workspace on the same screen?
Actually, since it's a "floating" window, can you move it with click&drag? If not, my guess is that it's **definitely** not a real window.
