AFAIK you'd just be getting lucky with SNA, as opposed to UXA. However, for the SNA slowness, you should file a bug and include the following information: lspci -n -s 2.0 /var/log/Xorg.0.log dmesg with drm.debug=0xe sometime after experiencing the slowness <feel free to mention UXA is much faster> -- Ben Widawsky, Intel Open Source Technology Center
