Symptoms

Game loads up fine and as long as you do not switch away and come back there seems to be few if any issues. But after switching away when you come back you can click some game elements such as HUD, but you cannot interact with the map or units on the map. Issue is sometimes intermittent.

Reproduction

Launch Warlock and start a game. You should be able to click on units and move as normal. Switch away from the game and then switch back. You should still be able to click on HUD items like menus, side notifications, however when you will not be able to select a unit by clicking and if a unit is already selected the mouse will not update the pathing or allow interacting with other objects on the map.
