i learnt what xkb does with the state.

use the state from keyrelease events directly, rather than query the state (which is not as accurate!)

the xkb state (as opposed to the normally sent compat state) contains extra info like the keyboard group, the pointer buttons, etc.  so we can just strip that stuff out. (See section 2.2.2 of the XKB proto document)
