After pressing a key, I need to press another key twice for it to trigger.

This issue is rather tricky to explain, but I will do my best.

 

Everytime I'm in-game, (i.e. actually moving around and such, not in menus), I need to press a key twice for it to take effect, when I've already pressed down any specific key. What this translates to is, If I press W and start moving forward, any other key I press after it, let's say Space Bar for jump, it doesn't work. Instead, I need to press the key I want to use twice, for it to actually trigger. So, in the end, If I want to jump, I gotta press Spacebar twice (jumping after the second press, and not the first).

In the past, and mind you this is a new laptop I bought three months ago, I had no issues with minecraft on my Desktop.

 

1. Press W to move forward

2. Press Spacebar once - doesn't result in jumping.

3. Press Spacebar again - It does jump.

 

This happens with any and every key. For example, the same thing happens If I press W and D. I need to press D twice to actually go right.

Another example. If I press A, I start going left, but If I press W, I need to press it twice to start moving forward.

 

This only happens on forge. I removed all my mods and still I have this issue. I have the latest version of forge.
