Hello, I have a problem: when I watch videos flickering lines appear on the black sidebars. They usually have the same colour as the pixels ajecant to the black sidebars. I can't "hold them in place", they disappear when I pause the video. They also only show up in full-screen mode.Tis happens on multple different sites.

Thanks for your help.

Hi, make sure your graphics drivers are up to date, and try turning off hardware acceleration as shown in Upgrade your graphics drivers to use hardware acceleration and WebGL

Also try disabling hardware acceleration in Flash, as shown in Adobe Flash plugin has crashed - Prevent it from happening again

If your question is resolved by this or another answer, please take a minute to let us know. Thank you!
