Without looking at the GMail details, you don't know period, so you should neither agree nor disagree. Others who do know have chimed in. For example: "1 is not even close to true. I was a Gmail SRE at the time. Sends did not take 5 seconds at the time, they were handed off to the MTA right away. The MTA had the ability to delay delivery due to other projects and Gmail decided to use that feature to build undo send." So, not a bug. As for Space Invaders, the game designer, Tomohiro Nishikado, knew about the issue from the beginning, and specifically chose not to compensate for the change in rendering speed. He could have easily done so. He liked the way it played. When you intentionally design a thing a certain way, it's not a bug.
