Buggy full screen mode since Flash 18.0.0.204

  • 772

I use Flash Pepper with Firefox via Fresh Player.

The following setup allows me to watch YouTube videos in full screen mode:

  • Kubuntu vivid with all the latest updates
  • Firefox 39.0
  • Flash 18.0.0.194 (Pepper, from Chrome)
  • Fresh Player 0.3.1 (from webupd8)
  • either the nVidia driver 340.76 or the Nouveau driver from vivid

When I update to Flash 18.0.0.204 or 18.0.0.209 all YouTube videos play in a 2mmx1mm box in the top left corner of my screen.

This can be reproduced with a live USB of Kubuntu vivid.

Does anyone using Flash 18.0.0.194 (Pepper) has the same issue? Is Chrome/Chromium affected too? Any idea on how to solve this (beside reverting to Flash 18.0.0.194)?

    Right-click on the lower right corner on any YouTube video, click About the HTML5 player and on the next screen tick the check box so your screen looks like below:

    Then you're not using any flash. Just HTML5.

    I uninstalled Flash a while ago and haven't looked back.
