After installing the 1.3 update and playing I encountered two graphical bugs that I never experienced before. At this time I do not have any details on what I was doing when they happened.

The first graphical bug had the mini-map not properly erasing the view box. So whenvever I moved the view using the mini-map the map would get covered in non-erased view boxes. So as I would drag the box around it would leave a trail of light blue which very quickly covered the entire map. I tried toggling on/off the different mini-map options, but the only way to clear it up was to save and reload the game.

Later in the game the mini-map again got corrupt. This time the entire mini-map graphics went corrupt. It was all "garbled" looking. Hard to describe. You could vaguely make out the map. I again had to save and reload to correct the issue.
