Syndra Bugs

I've been wondering if this is just for Syndra or more champs. During a heavy team fight, especially in jungle, after killing an enemy opponent with Q, W, E, or R, with locked screen, Syndra will begin rubber banding. This effect is highly annoying and repetitive. My whole screen will begin jittering, which forces me to unlock my camera (pressing Y) and has gotten me killed many times because of the fact. After the camera has been unlocked, Syndra continues to jitter as she did before, it's just less hindering for me, because now only the champ is jittering, not my locked camera.

Furthermore, I have noticed new bugs like: After ulting or something crazy it will show that my W is available, but I am unable to pick up a ball that's right near me. Either the W is glitched or the ball? I never, however, have issues with Qing somebody, Eing a Q, and ulting. The only Glitches are the jittering Champ after kill, and "invisible" balls. (these invisible balls have also cost me games, and deaths).

What I would like: Feedback from other Syndra mains, do you experience these problems too? I'm not a forum guy so if this is in the wrong format or section I will never post anything again, but I just wanted to get my frustration out.

Best Regards, Max.
