Re: [Intel-gfx] Fighting tearing
Well The tearing is so noticable that even my friends notice it, without compositor, only I notice it, but it's very annoying and distracting to my workflow when moving windows quickly.

If I just replace UXA with SNA. Is the tearing fixed though? What happens when you test different Window managers or some live distribution with other versions? You can even test those by saving the ISO file on your drive and directly boot those using GRUB 2 [3]. Thanks in advance for any help. I am sorry for not being more helpful.

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 ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx

I also experience tearing when viewing web sites with chromium and scrolling downwards webnewspapers etc. Hope this adds more relevant info.
