The problem An posted on reddit.1 I have my window numbers in my modelines of every window so that I can easily navigate to them with my exwm three-monitor setup. About 90% of the time they are accurate, but they get out of sync sometimes when big window operations (or closing a window) occur. As soon as I do something to invoke a mini-buffer (any C-x command), they get updated correctly, but sometimes when I try to work quickly I find they don’t match up.
