HTML5 Video is Very Laggy
Playing videos in the small or large player is fine, and 60fps videos look nice and smooth, but when I fullscreen, the video drops down to about 27fps no matter what quality it is, and the player itself gets really unresponsive while the video is playing. It takes several seconds to pause, and all the animations are very laggy. Strangely, when I unpause the video or pause using the spacebar, the video reacts almost instantly, but the animation in the middle of the screen is still laggy.
Note: Playback in chromium is fine, and hardware acceleration is disabled because when I enable it, it makes visual artifacting, tearing when scrolling, and extreme lag.

PC Specs: i5 4690k (integrated graphics disabled via BIOS), radeon hd 7950, eluctronics 500gb pro ssd, gigabyte z97n-wifi, linux mint 17.2
[EDIT]: At 1080p 60fps large player mode (theater) the player's animations will lag, but pausing/unpausing will respond immediately. In this mode the CPU usage ranges from 30 - 75% on each core, which is absolutely absurd, considering my hardware.

Do you have the latest Flash Player (Linux) Version 11.2.202.508

check this:
- see if there are updates for your graphics drive drivers

- disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?
As said in the title, this is HTML5 video we're talking about, not Flash. That said, I do have the latest flash. I also have the latest drivers, but that wouldn't even matter since acceleration is turned off. Running "firefox -safe-mode" does not fix the issue.
Videos are also very slow to maximize and unmaximize.
Guys, get your stuff sorted out. Having media optimization as awful as this is just not okay. Every other browser I've tried - the mint default browser, chromium, opera... they all do it just fine. You can't even fix all the problems with video acceleration! And the only response to this problem is a random user copy-pasting an irrelevant part of the Q&A section, and nothing else? I have an i5 4690k and I can't even decode HD video at 60fps? What's going on here?
Just because Linux users are in the minority does NOT mean that you can go ahead and put in the least amount of effort possible to get it to load a web page and then call it done.
