Huh, I think my water is having the same problem
thelaststand's is, is there an easy way to take a screenshot in-game?
Also, something that's been happening for a looong time but I've never thought to mention it is:
The vision radius of moving units lags for me, even though nothing is lagging. It's like the vision radius only updates once a second or something, so it looks super choppy, is this a bug with the game or with my computer? I'm not 100% sure it happens every game since by now I've gotten used to it, but I think it does.
