Since today's patch 1.1.2259 (aka Hotfix #3) attempting to pan the camera around using middle mouse button while having a tool for delivering commands active (Chop Wood, Harvest Plants, etc) frequently causes the viewpoint to jump to the top-left corner of the map.
Seems to only happen when you are panning the view up and to the left with one of these command tools activated -- then the camera will just jump up there.
Behavior does not occur when no command modes are active.
Steps to duplicate:
- Click Architect
- Click Orders
- Click Chop Wood
- Try panning the camera around using middle mouse button. Moving the camera toward the upper left corner of the map will usually result in the view suddenly jumping to the top-left corner of the map.
This behavior occurs with no mods active. I did not include a save file because I could duplicate the behavior on any loaded save or any newly created game.
Here is a video of the described behavior:

In the video I begin by rapidly moving the screen around with a "default" mouse cursor to show that the described behavior does not happen in this mode. Next, I activate some different "command modes" (such as Chop Wood) and pan the camera around to show the bugged behavior in action.
