I want to play Osu using my keyboard. But every time I play a song and press either Z or X, the cursor just freezes where it's at and it doesn't let me move it until not even a second later, thus making me fail the song. It also happens when I'm NOT playing a song. Every time I press Z or X, the cursor freezes for a brief period of time. It's starting to get on my nerves seeing that thing freeze when I'm trying to play on keyboard mode. How do I fix this?
