The blind spot portion is what I've experienced, but none of the rest. No flickering or even noticeable expansion. I was a kid at the time and was playing an FPS. At one point I realized that I could see all 4 corners of the screen, but a certain sizeable area inside it was not visible without me moving my eyes. It provided for an interesting gaming session, but did go away rather quickly.
