Hi, I have been having an issue with Minecraft. For some reason, many times when I right click to place a block I will place two blocks instead of one. Usually when this happens, there is a lag spike visible on the f3 performance graph. Oddly enough, however, when I set the view distance to far the problem tends to happen less frequently. Please leave a comment if you know more about this than I do, I would love some helpful tips on how to prevent this. Thanks! UPDATE: The problem seems to have gone away now that I have more RAM on my computer.
