As said before I'm willing to help with debugging and testing.
If someone knows how to debug this please let me know.

On my laptop I can easily reproduce it by following these steps:
- install chromium browser:
$ sudo apt-get install chromium-browser
- install the Adobe flash plugin (you might need to enable the Canonical Partners repo)
$ sudo apt-get install adobe-flashplugin
- open Chromium browser and go to youtube or any other website with flash videos
