I often had trouble with Ctrl and Shift modifiers while playing games (maybe this is gnome specific). For example if I press and hold Ctrl to crouch and I press 3 to select some gun while crouching I get in game menu (which is triggered by Esc).

Remove bindings (keys will still work in game)
add bindings back again after you are done playing game
