Zac E channeling bug

I have played over 50 games of Zac on this patch and his E is extremely bugged. I imagine it's the same issue as Vi and Pyke are facing, but I wanted to make sure riot knows Zac has it too. about 1/10 times when I'm channeling his E, it will suddenly stop without me releasing the key, and I will lose my cooldown and "leap" in place. It also sometimes doesn't release the jump when I release the key. It is absolutely devastating to charge up your E to jump over two walls into battle, and instead jump in place and have to walk into the already lost fight. feelsbadman. Since Zac's entire kit revolves around his E it makes him feel unplayable.
