Input sometimes delayed

I exported my game to EXE and WEBGL, and sometimes when you press a key, the input doesn’t trigger. It makes the game harder and it’s just overall very annoying.

Maybe that can help you:
Input values are floats between -1.0 and 0.0 / 1.0 and 0.0.
If you are checking for equality there can be a problem.
Try using >=, >=.

Are you testing in Update or FixedUpdate?
