Problem: Moving windows, accessing the Activities overlay etc. is jerky and not smooth.
I'm running Ubuntu Gnome (hey, soon I'll just be able to say Ubuntu!) on 17.04. My hardware is a 4k screen with
Intel® HD Graphics 530 (Skylake GT2) running on
i7-6700HQ CPU @ 2.60GHz × 8 with 16GB RAM.
I don't think it should be jerky.
What I've tried
I've tried uninstalling
xserver-xorg-video-intel, as recommended on a redit post (which refers to a note on a Debian package saying it's deprecated), although I could not find the
xorg.conf.d/20-intel.conf referred to in that post. There was no noticeable difference.
I've tried running the Wayland session. (click your name in the gdm log in screen, use the cog icon to select Gnome on Wayland, then enter your password). If anything this is worse, although I have no way to measure this except my eyes.
