I've been watching Netflix in Google Chrome for months without any problem. Since one of the last updates however, there are weird graphical glitches. If you start a stream, you can only hear the audio. Otherwise the screen remains black or will just show the preview pic, and if you start hovering above the timeline with the mouse, the little thumbnails that pop up will stay. Also, if you scroll down in the menu you get the same effect. It looks like this:
I'm using Google Chrome 50.0.2661.94 (64-bit) on freya 0.3.2. So far as I know it is the current version. I have an i7-6500U CPU and an AMD Radeon R5 M335 graphics card. I've tried other videos, they work fine.
