Don't know if this a bug per se, but my downloaded videos are starting to buffer a lot. I went ahead and downloaded the Nvidia update, in case it was my card. That seemed to break my audio, so I eventually fixed that. Restarted my PC... since that seems to be the thing you do after you change things. "Downloaded" the video again, and it's still buffering a lot. This was happening a lot a few months back, but then it seemed to go away when I got Gigablast, so I attributed the better performance to that, but now it seems to be back. Windows 10, Chrome.
