White square over launcher

Bug Description

I regularly get a white square under the panel over the top part of the launcher. It does not appear every time, killing it with xkill terminates the desktop of launcher beneath it (like it isn't there).

Only solution when it appears is either a restart or logout/login. Closing all apps one by one does not get rid of it.

See screenshot
