Say I get an upvote on an answer. +10 indicator shows up, great, I click, click out, it's gone. Then if I click to a different page, or refresh it, it'll pop up for a second and then go away without my doing anything. It seems to get quicker with more refreshes. This happens a lot, but not every time. Why does this happen? It strikes me as very peculiar.
Using google chrome on an old acer chromebook 11. (It dual-boots linux, but I'm loading the page on the chrome side of things, so I don't know if that would actually affect anything.) Happy to provide any more system information necessary.
