Current Behavior

Intermittently, when switching focus between windows using keyboard commands, focus will get "stuck" on a window. When this happens, pressing a key to shift focus will briefly move the focus to the correct window, then it will snap back to the previous window. The snap-back happens on key release.

I have seen this behavior pop up in both single-monitor and multi-monitor setups. Shifting focus via mouseover reliably unsticks the window. If I create a new window, the behavior subsides until I close the new window -- after that, the same "sticky" window starts misbehaving again. Switching to another workspace and coming back also does not "unstick" the window.

Reproduction Instructions

Unfortunately I have yet to figure out a reliable method of reproduction. I'll keep working on this.

My i3 config can be found here

I'm using Arch, no compositor.

I also have a Debian testing machine which has the exact same config and version of i3, but does not exhibit this problem.

This issue might be due to my use of unclutter. I replaced it with Airblader's unclutter-xfixes. I'll close this issue if that solves it.

I haven't had any issues with focus since making the switch, so I'll close this out.

Thank you, maintainers, for all your work on i3!
