My right click is being odd with Minecraft?
That really does sound like a hardware issue, where your mouse lags to fire the 'mouseup' event on your right click.
Here is the test for you: https://www.onlinemictest.com/mouse-test/ You should see your click turn blue the moment you click, and then become paler the moment you release. My guess is you will see it stay dark blue even after release.
If you do: Well, not much to do with that. You 1- Manually do a repair of your mouse or 2- change your mouse.
