Gameplay Vision Issues Blitzcrank

During a recent game of League of Legends, i was put up against a Blitzcrank bottom lane. One of the most critical things to do while playing against Blitzcrank is to dodge his pulls, however this is nearly impossible when they can't be seen. I noticed a vision-related bug which causes being unable to see Blitz's fist during his q ability. I noticed this after the implementation of patch 5.5.
