mpv window doesn't spawn when launched via webtorrent or play-with-mpv apps

When I manually run mpv it opens up normally, while when I run applications like webtorrent or play-with-mpv the window of mpv won’t spawn and it keeps running in background (while I can hear the audio). I don’t have any issues when the same application launched with vlc option.

Great. Thanks for confirming.

[elParaguayo]

I’m referring to the error message in your first video clip which shows that qtile crashes because it can’t parse the window name. That error stops a window being created but you’ll still hear the audio.
