CWC Scorching Ray/Whispering Ice(Icestorm) Casting Feathered and Unusable

Reference number: 4,063,352,447 (also contained within Screenshot).

Half the time when i get stunned (lots of multiple small stuns) whilst channeling scorching ray, the channeling process becomes feathered in the way of the casting and halts multiple times as if i am being consistently stunned. this happens and continues to happen even when there are no enemies around and only when i continue to cast the skill and requires me to stop and re-cast it.

Furthermore, i performed some testing and found i could 'proc' this and achieve the same result by pressing the skill button ('Q' in this case) multiple times in quick succession and then immediately holding that skill and it continues to be used in that fashion as if i were still pressing that skill multiple times. The reason why i mention stun is because this is when i really noticed it happening as it has a similar process and the same result as the testing aforementioned.

Here's the screenshot:
