Description of problem: When viewing a flash video in fullscreen mode, the video is very laggy. Version-Release number of selected component (if applicable): 0.0.16 How reproducible: Always 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) 3. Actual results: Very low fps Expected results: Smooth as it is when not in fullscreen Additional info: 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!!
