I'm following along with the code given on Day 002, but I seem to be getting the weird repeating pattern shown in the image below. The larger white rectangle appeared when I opened the Windows 'Start Menu' and covered the aforementioned area. The squarish black area appeared when another window for a screen capture utility was put on top. Dragging the created window around results in even more severe corruption! Could somebody help me figure what's going on?
Please see imgur for what I mean.
