After hitting the “control” key, the camera is locked into the frame it was in when they key way hit. Any movement of the camera from either the clicking the mini-map or dragging the cursor to the edge of the screen violently jerks the camera back to the original position where the “control” key was pressed.
This issue also occurs in Starcraft 2
Restarting the game and battle net client do not fix it
There are no key bindings that should lead to this
Continuously holding the “control” key does allow for free movement of the camera but when the key is let go the camera is now stuck on that position
