Check the 'ttymouse' setting. The "xterm" mouse protocol doesn't support
columns beyond 223.

I'm using gnome-terminal and my vim automatically detects this and sets
ttymouse to sgr, which doesn't have the 223-column limit.

Try manually forcing :set ttymouse=sgr, see if that helps.

Assuming it does: I don't know if vim can autodetect Konsole, given that
it self-reports as xterm 115. According to :help 'ttymouse', the sgr
protocol was added in xterm 277.
