Re: NVIDIA, please, fix Adobe Flash 10.2.x and 10.3.x
I think sandipt was only referring to YouTube videos leaking through all blackness. Everything fits: it's using an overlay and not hiding it when the window is not on screen. And I would agree that Flash should be fixed.
However, allowing video decoding through /etc/adobe/mms.cfg leads to Xorg hangs on video sites other than YouTube (different sites use different codecs, YT is not affected). As I mentioned, I can do the same with mplayer -vo vdpau -vc vdpau on specific files. Those are user-mode applications causing system instability and it is indeed exploitable. I believe this should be addressed by Nvidia.
