Description Mehmet Kose 2013-08-17 15:02:27 UTC
PepperFlash 11.8 cannot play YouTube videos smoothly. One frame per second when I try to watch 480p. I can download these videos and watch with vlc just fine. HTML5 video playing also works much better than Flash.

Same hardware has no problems when running Ubuntu 13.04 (or 12.04 with backported Xorg packages.) 12.04 out-of-the-box  just like FC19.
I couldn't find what they did differently, it's over my head.

They are attempting to use OpenGL, and the driver cries out in disgust because the hardware cannot do what they ask for and so falls back to software, which as you have discovered is over an order of magnitude slower.

The best workaround would be to disable "hardware acceleration" in Chrome/PepperFlash.

Closing then since it seems not supported. Otherwise reopen please. Thank you.
