[Intel-gfx] SNA questions
Hello Is SNA still under heavy developement? Is the performance still being worked on? Regards, Roberth Sjonøy ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
Re: [Intel-gfx] SNA questions
Hello Are you psychologist? /joke I wonder if it's planned to be faster, because beside the performance it works very good for me with the right settings regarding the tearing issue. If performance is still under heavy developement?

Re: [Intel-gfx] Fighting tearing
With the WM I use (xfce WM 4.10.0) with it's compositor, the tearing is much less, but the little tearing who exist is very noticable.

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.

X's rendering model, in the absence of a compositor, has no concept of vsync. It's simply not possible to not tear. - ajax ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx

Hello What can I do then? Wait for SNA to mature more? Other settings with UXA or SNA?

Re: [Intel-gfx] Fighting tearing
I also experience tearing when viewing web sites with chromium and scrolling downwards webnewspapers etc. Hope this adds more relevant info.
