[GAMEPLAY] Smart Ping Selection Bug

I am experiencing my cursor changing direction and locking at that direction when I move my mouse in the Smart Ping interface. It does not happen every time, but it does happen quite often. This bug will continue to lock my cursor at a direction until the ping is made or cancelled. Once again, that process is:

1. Hold G (default hotkey)
2. Left click and drag cursor
3. Cursor will change direction after going a short distance, and possibly accelerate in movement My Operating System is Windows 7, and my mouse is a Razer Naga 2014. I have already filed a ticket and have had no such luck with the possible solutions. If you have any suggestions, I will certainly be open to trying them.
