Graphics getting stuck after 47.0
It's most noticeable on tumblr, where boxes get stuck after they should disappear, but I've seen it on other websites and in the interface itself. The loading bar on youtube getting stuck after the page has finished loading, the download arrow graphic getting stuck after saving something, etc.
Hardware acceleration is disabled. attatched some screenshots of examples I've run into so far.
