After upgrading from Fedora 21 to Fedora 22, vim no longer changes konsole's title when run within a konsole. Title changing still works properly if vim is run within an xterm. I'm using vim version 7.4.640 Reproducible: Always
Works for me for the *tab title* with Konsole from git master. The *window title* is not expected to change though. Please re-open if you can reproduce this issue for the *tab title* with Konsole 18.08.x or git master.
I got it work work by going to "Settings > Configure Konsole > Konsole Window" and turning on "Show window title on the titlebar".
Perfect.
