I bought a Acer Chromebook 15 (CB3-532) in February. Use it only for surfing web, and not very often. Have added no browser extensions, etc. Installed no software, downloaded no apps. Strictly stock use via chrome browser that came on machine. A couple of weeks ago an issue started arising when playing embedded videos on websites or streaming video. The video window goes completely green. Audio is unaffected. Googled and saw this has been encountered, but mainly when using chrome browser on windows machines, and work around was to go into settings and disable hardware acceleration, but this is not an option on my chromebook. Have tired a few other suggestions I saw online, including clearing cache, restoring factory settings, doing a full "powerwash" restore, and some kind of hardware reset by holding down the circular arrow key above the number 4 on the keyboard while turning on the chromebook. All of these seem to fix the problem for anywhere from 2-20 minutes, and then problem returns.
Need help!! Thanks!!!
