Comment 161 for bug 967091

Anders: You have no stability issues with Flash Player? What CPU are you using (does it have multiple cores and/or hyper-threading)? I am asking because there are too many reports of EnableLinuxHWVideoDecode causing instability, that I doubt it is actually related to a particular GPU.
However, trace log by swiftgeek – http://pastebin.com/tJrXXqFk – could point to a race condition in Flash Player, which could be emphasised with multi-core CPUs.

Also, if you are using recent Google Chrome beta or unstable, always check what version of Flash Player is active (chrome://plugins). Pepper (PPAPI) version of the plugin was recently added to beta Chrome; PPAPI Flash is using full hardware decoding so it doesn't show this bug. It still has other issues, though.
