xprop trayer говорит примерно следующее:

Не совсем понятно отстутствие полей вида _NET_WM_STRUT.
Были бы _NET_WM_STRUT или _NET_WM_STRUT_PARTIAL, тогда avoidStruts понимал бы, что trayer нужно игнорировать.
Сперва грешил на xmonad-contrib-9999, но дело, видимо, не в нём. А в чём?
Для интересующихся, версия `trayer --version` == `trayer 1.0`.
