It's more like a feature than a bug in my opinion... but yeah, I'd like it to be changed as well, so that the animation (not to mention the log) would be unaffected by this 'blinking' which in itself is a rather annoying feature.

If they could at least make the character outlines to stay visible, or something like that, I think it would be a lot better all in all but it's probably not too easy of a feat to do due to how things are built in the game... unfortunately.
