I don't think a screenshot would be helpful, but whenever I'm on a planet with a drone or in the test flight, it seems that the game thinks I'm pressing a key even though I'm not. This only happens if I already pressed the key once and i can only stop it from doing it if I press the key for a short while then let go. Sometimes it even thinks that I'm tapping the key over and over. I know it's not a keyboard issue, because if I unplug the keyboard while this is happening it still happens. I am on Ubuntu 19 64bit and using version 0.3.0 closed alpha.
Sorry if this sounds confusing, you should ask questions.
