Close the game :)

ALT+TAB out of it?

Have you tried bringing down the console or pressing alt+tab? Works for me.

+1 bring the console down

Alt+Tab hasn't worked, will try console when i get home from "work". Mainly trying to stream Q3 / Defrag but having OBS issues configuring monitor capture. Works fine for CPMA / QL, but Q3 is giving me all sorts of headaches.

TYTY! :O)

You can also make a bind to toggle in_nograb.
