Incredible that this issue still hasn't been solved...
I've had it for months, and it is seemingly random.
The problem I have is that the video slows down while the audio continues on like normal. After 5 seconds, the video is almost at a standstill and the video begins to "buffer". I say "buffer" because the video has already buffered, but I still get the loading animation. After 2-3 seconds, the video starts playing and the problem repeats itself.
Sometimes it disappears when I refresh, sometimes it disappears if I let it do that 5 times over... but it is seriously a major issue that needs to be resolved.
What kind of "gamer" browser can't play videos properly?
