Why are some in-browser videos suddenly artifacting like crazy?
December 5, 2015 8:03 AM   Subscribe

Recently (in the past month, I think), when I watch videos in a browser window sometimes they will develop a pattern of thin horizontal artifacts, as seen here. The artifacts are not static, but change color and position as the video plays, and will generally take up more and more of the screen the longer I let it go. I can't figure out what's causing it or how to fix it, nor can I find a workaround.

It only affects certain sites - for instance, all Vine videos are artifacted, but YouTube works fine. The affected videos are not all Flash-based, for instance. It affects Chrome, Firefox and Internet Explorer 11, and does not appear to be a GPU error - disabling hardware rendering has no effect. Plus it didn't coincide with a new graphics driver and installing a more recent one didn't fix the problem. I'm on Windows 7 and using a Radeon 6670 graphics card.

I might try toggling the Use hardware acceleration setting, if your browser has it. That helped me when i had a similar problem in Firefox.

What is your power supply? What is the temperature inside the case? Can you reproduce in offline videos?

Response by poster: Huh. Even though starting Chrome without hardware rendering did nothing, turning off hardware acceleration solved it. Strange. And it means I may have a graphics card problem after all.

You probably just need new drivers from AMD.
