Mac Client Stops Receiving Clicks

I cannot seem to reproduce this consistently. Sometimes it happens after I send a chat (post pressing enter), sometimes after pressing recall. Perhaps it's related to bushes? I'm still trying to identify it. However, this is a bug where the game stops receiving mouse clicks of any kind. All keyboard functions remain fine, and mouse movement is fine, but clicks DO NOT register. The only way to fix this is to force quit the client and log back in.

This has happened at least half a dozen times in ranked games.

I'm on a 2014 Macbook Pro, using an external mouse (razer).
