Q:

Glitch / Blink video on OSX (Macbook pro 15' mid-2012 no retina) and firefox 40+

I currently have a problem with my macbook 15' mid-2012 (No retina) with Yosemite. When I watch videos (e.g. Youtube) via Firefox, sometime for a microsecond the video becomes blue then comes back to the original color. This problem happens randomly; therefore I have no idea if it's come from Firefox, Youtube or my macbook. I tried with safari and this problem didn't happen, but I can be sure.
Moreover, other problems have appeared at exactly same time. It might have a link. My macbook has accidentally rebooted and hasn't produced a log. Finder has accidentally stopped and hasn't been not able to restart.
I have did a complete reinstallation of OS X but the problem is still there. I have also execute an Apple Hardware Test, but all seems ok. Yet I have suspicion of a bad RAM or GPU. All my softwares are up to date.

Could you help me in this matter ? Thank you.

A:

I finally found what was the problem. Firefox has an option "hardware acceleration" which seems to not be stable. It allows to use GPU instead CPU when it is possible.
