Whenever I am watching a video through Opera and I move my mouse, the video starts jittering badly. The audio stays 100%. Chrome does the same, but Firefox performs fine.

I have a i7 7700k, Geforce GTX 1080 and 16GB RAM. My laptop, which is an i7 4600U, Intel on-board GPU and 8GB RAM plays everything fine.

If anyone knows what's going on, please help, as I love Opera.

I have the same issues, but funny enough, only when I move my mouse.
