Firefox youtube html5 video slow, choppy on Linux with intel XNA AccelMode in the Xorg settings.

Posted

Hello, dear Firefox team. When using SNA as the preferred AccelMethod in the Xorg for my intel i5-5200U I get fine firefox performance, but my system runs bad as a whole. When I switch to using uxa my runs great but firefox run slow and choppy and it's impossible to watch html5 video. Just though you should know.
