[GAMEPLAY] Skillshot indicators persists

Im not sure how descriptive i can be with this since it only happens in intense teamfights where my focus is pretty much not at all on my skill shot indicators since i know where theyre gonna hit. I only notice them because they persist and it messes with me. Usually, i think the shot has already fired, but the indicator is still there, cause when i go to left click nothing happens other than the indicator disappears (im really really hoping my skills have been going off). I have my skill indicators set such that they show when i hold down the skill button, and the skill fires once i release the button. Im also using quickcasting by default (so no holding down shift or anything or wahtever people use when they have quickcast by default disabled). Although sometimes i end up holding down the shift button for attack move clicks. I wonder if my mouse is interacting with my skill shots in a weird way? I have no idea.

Anyway, its kinda a nuisance. It really messes with me during a teamfight/skirmish.
