Enabling/disabling camera lock causes the game to freeze

Heyo,
along with my persisting issues with FPS, the latest patch has started causing camera lock toggle to freeze the game completely for about .5 to 1 seconds.

This is kinda bad, because I like to play the game using camera lock, but tend to switch it to disabled quite often depending on the situation.

Is this a known issue with the newest patch, or is it just me?

EDIT: seems that holding down spacebar to follow the hero doesn’t cause this behaviour.
