Following the reproduction instructions from https://github.com/i3/i3/issues/3242#issuecomment-436175346 For me, #3242 happened when the following sequence executed: 1. Fullscreening window correctly calls `stop_child()` in6e24e2ad6f/i3bar/src/xcb.c (L685)2. Xrandr change, `reconfig_windows()` is called and `output->visible` is set to `true` in this line:6e24e2ad6f/i3bar/src/xcb.c (L1791)3. When the window's fullscreen is disabled, `handle_visibility_notify()` returns in this line:6e24e2ad6f/i3bar/src/xcb.c (L677)because previously `output->visible` was set to `true` To fix this, I call `cont_child()` more leniently since it is a no-op when the child is not stopped. Fixes #3242 Closes #3761
