While the stated version may fix open bugs, for me it also locks up the browsers on any page having flash until it times out. Can't play videos on Yt, games on f.e. kongregate.com and notdoppler.com also don't work. Happens in both, Opera and Chromium, flash is built with USE="64bit multilib sse2 -32bit -debug -kde -selinux -vdpau" Kernel is 3.9.6 and nvidia-drivers is 319.32 (can't update those, grml). Reproducible: Always
For whatever reason, a reboot fixed it - sorry :(
