Can we get some insight into bugfixes for Syndra's -often- gamebreaking R bugs?

Patch 7.10 introduced a way more severe version of her old stutter step bug. After casting R, her model desynchronizes from the game world and glitches around, and the spheres start teleporting around and become untargetable by W or E. I've seen the bug trigger even in LCS games and yet no one noticed somehow. This bug is often gamebreaking when you lose teamfights because you can't cast your spells properly. Can we get some insight into bugfixes?

Edit: i obviously made a thread in the "report a bug" section, but i got no answers nor visibility.

Edit 2: new, fresh clip from the first game i played today. https://www.youtube.com/watch?v=zuq6wb2ed9c&feature=youtu.be
