I recently installed i3 and so far I'm loving it.
There is just one small thing that still put me off: when I open an application through the terminal (I tried with the default Gnome terminal and Xterm), it opens the application and a strange window (the screenshot provided is when I opened vsCode, but the issue is similar with Firefox for example) It does not take much time to close it (especially with i3 shortcuts) but it is still a little annoyance that I'd love to get rid of...
From what I've found online (I couldn't find anyone that has the same problem... but I might not have looked at the right place just because I don't know for sure what this window is), I think that this Window is GTK Inspector...
When I switch to my default Firefox profile, the issue disappears. I searched through my config files and I find no mention of GTK something.
The window closes as soon as I exit the app I opened. Using wmctrl -l doesn't show this strange window.
