Minecraft 1.8+ clicks don't work.

[Saprix]

Hey guys so I'm going to talk a bug in my minecraft. It's not a Vape bug.

So my clicks in 1.7.10 minecraft works fine but when I'm on 1.8+ versions my clicks sometimes stops. Btw my mouse is not broken it work very well.

When I combo someone my clicks work fine.
But It's hard to get the first hit with this bug.
