I have the same trouble - swiching occurs on press, but not on release.
I looked events with xev utility:
$ xevKeyPress event, serial 34, synthetic NO, window 0x4600001,
root 0x7b, subw 0x0, time 52934768, (315,42), root:(1081,421),
state 0x2000, keycode 37 (keysym 0xffe3, Control_L), same_screen YES,
XLookupString gives 0 bytes:

state 0x4, keycode 37 (keysym 0xffe3, Control_L), same_screen YES,
XLookupString gives 0 bytes:

...
Is it possible to fix this? To move switch to KeyRelease event?
