Mouse button input not always registering...

[PixelTwitch]

I have only started with this problem today… After the load test started…
Was not all the time but enough to become frustrating…
Happened with 2 mice…

You left or right click and the action does not happen until you repress the button.

My mouse clickers themselves broke today. Didn’t have any problems like this using my trackpad though.
