Jet controls messed up in season 1 mouse movement overrides pitch up key

The aircraft controls have been messed up in season 1. Any little mouse movement up or down overrides the 'space' key that is bound to pich up. Now if I pressing space to continuously pitch up and I move the mouse just a little bit the aircraft is not pitching up anymore, just if I press space again and don't touching the mouse.
The double input was fine before now that's not a possibility anymore. We have to chose between flying with mouse or with keyboard. That's so bad that either you will run on of mouse pad or can't aim properly.
