Re: NVIDIA, please, fix Adobe Flash 10.2.x and 10.3.x
As lexa2 observed in RC1, final release of Flash 22.214.171.124 also disables hardware acceleration even if it's turned on in the settings. Guess that's better than leaking through black.
I'm not trying VDPAU since you've confirmed it breaks the system just as with Flash 10. I'm a Linux user, gotta cherish my precious uptime! ;)
