I spent some more time looking into timing attacks on CSS Shaders. I haven't created a proof-of-concept exploit, but I believe the current design is vulnerable to timing attacks. I've written up blog post explaining the issue: http://www.schemehostport.com/2011/12/timing-attacks-on-css-shaders.html Jonas Sicking seems to have a similar concern: https://twitter.com/#!/SickingJ/status/143161375823380480 It's probably worth addressing this concern sooner rather than later. Ignoring it certainly won't cause the vulnerability to go away.
