Problem with HD youtube videos in google chrome?

[689]

Whenever i watch a video in HD on youtube it starts to display this weird green and purple stuff and i can't watch the video. the sound is fine and my connection is fine, there is no buffering and this wasn't a problem until recently. As soon as i put the video back to 360p it displays the video perfectly.

How do i fix this issue?

A GREEN screen is a sign that your Cache, Virtual Memory or PageFiling is filled-up
and can't take any more, especially if you've viewed a lot of vids.   Simply delete your
Cache, Cookies and History; then clear your Memory with a shutdown & fresh reboot.
Afterwards, you'll freak at how good and trouble-free your YouTube will be.

Don't forget to totally shutdown+reboot afterwards.

Other possibilities + solutions:
-- Turn off your modem AND router for 30 seconds, and then turn them back on again.
-- Right-click any video, click "Settings" and uncheck "Enable Hardware Acceleration".
-- Disable any Adblock add-on, play a video; then re-enable the Adblock the next day.
-- You might have a conflict with another player, (Chrome Pepperflash or Real Player).
   If that's the case, disable/uninstall it, and when you'd like it back, simply reinstall it.
-- Disable your AV utility while on YouTube, since you can't get a virus from YouTube.
-- You may unknowingly be using ''HTML5'' rather than "Flash''. To be sure, click here
