It happens with both Xwayland and native clients. Pointer focus is still usable, but clicking anywhere won’t restore keyboard focus, it requires the focus to change to another client (or surface?) and back to work again. Happens with Weston 1.10.90 on commit aab1d36, I haven’t tried previous versions yet.
