I have a small problem when the NumberPad pops up. One of the keys, usyally the number one key, is marked green. That is the mouse hoover effect. However, my mouse is nowhere near that button, or any other for that matter. I can remove it by hoovering the mouse and removing it again.
Also, you can control the hoover effect with the WASD keys. And if you removed the hoover effect with the mouse, and then use the WASD keys, the buttons turn green again.
I noticed that you have the same issue on your end in the video.
