Ability Echo Slash and Swashbuckle in Nest of Thorns in Linux seems doesn't work as expected, the "slash" particles looks like hitting the enemy units however no damage nor knock back being dealt or applied, it Echo Slash only deal damage and knock back when an enemy is in the radius or area of effect of the Echo Slash, much like Axe's Counter Helix

As you probably can see, in my case, the Echo Slash damages every enemy around Kez or I guess the hero, while in my friend's case, even the enemy at the back of the hero doesn't get damaged, it only damages enemies in front of the hero, just like where the particle effect is.

Steps for reproducing this issue:

1. Open Dota 2
2. Play Nest of Thorns
3. Pick Kez or any other hero then pick Echo Slash ability
4. Try to hit the enemy in front of the hero
5. Observe what happened
