Bug flicker Strike on Abyss boss

Hi,
This bug is common since 0.2 but happen all the time on the abyss boss.
This is due to the room or the height of the boss.
The character, when he do a flicker strike, doesn't hit from a side to another side of the character. When the bug appears, the charater just stick to the boss and hit very fast the boss. This cause to deal a lot less damage, and get a very bad flicker strike. Here is an exemple
