Description of problem:
When viewing a flash video in fullscreen mode, the video is very laggy.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Adobe flash-plugin 10.1.53.64
2. Play a video on youtube (eg http://www.youtube.com/watch?v=WlAHZURxRjY)
Very low fps
Smooth as it is when not in fullscreen
Switching to kmod-nvidia from rpmfusion solves the problem. So, it's definitely a nouveau issue.
Workaround: disable hardware acceleration. But doing that, HD video in full screen flickers (however I don't know if it's Flash or video driver problem). Anyway, disabling hw accel is not obvious for the end-user, so I would prefer to look for a better solution using the default settings.
That's working very well for me. Thanks!!
