Spotify stuck in fullscreen
I'm not sure why it happens, but from time to time I'll start up Spotify (in GNOME) and it will not only be in fullscreen mode, but there's no apparent way to exit out.
Even though the cause will probably remain a mystery, I did figure out how to get things back in working order. First, close completely out of Spotify.
Once exited, open up Spotify's preference's file in your favorite editor (mine's
nvim) which is located at $HOME/.config/spotify/prefs on Linux and look for
the lines:
app.window.position.height=#
app.window.position.width=#And delete both of those lines!!
Save the file and restart Spotify and you should be back to having a non-fullscreen Spotify!!
