Right click sometimes double clicks?

[Pvt.pile]

Sometimes when im playing the Iron Sight button/Right Click double clicks, ive cleaned my mouse reinstalled the software even reinstalled RS2 completely and it still happens.
This only happens in RS2 and War thunder does anyone else have this problem or know a fix?

And what kind of mouse is it? I use Deathadder Chroma, holding down right click to aim in and then have one of the side buttons to toggle aiming in while I'm in a waiting position. And if its a problem across multiple games then its probably a hardware issue, I had some sharkk mouse prior and it would spontaneously come out of the clicked in position, meaning I would be holding down my right click button to aim in and then it would just release while still being pressed in.
