That's a very different problem from any keyjamming problem I've ever
experienced. Just to be clear:

Depress Q
Depress W
Depress S
Release S
Release W
Release Q

Keyjamming problem: No events for S are ever sent.

This is a common problem, and this is the reason that so many games
use the modifier keys as buttons: because modifier keys are intended
for use in combination with other keys, they often get their own
circuits, which means they can be combined with more combinations of
keys.

I've never encountered a keyboard would send a KEYDOWN event for a
key, and then not send a KEYUP event even whenever *all* keys have
been released. You have a seriously shitty keyboard if that is the
case. Buy a new one! (Or, as I said earlier, replace the keyboard
controller!)
