Hi,
I just finished setting up Arch on my desktop and getting GNOME installed. Unfortunately, the accessibility tools - the main reason that I installed GNOME - are giving me trouble. Whenever I enable magnification (even 1:1) the cursor's movement becomes incredibly choppy. The only comparison I can think of is playing a video game at about 20 FPS. Everything else is just as fast as usual, but the cursor is so slow and erratic that I have trouble using it at all. I've seen a couple of other people online with this problem, but found no solutions. Since I'm legally blind, I need this feature to work in order to use my computer, and both Windows and OS X provide excellent implementations. I want to switch to Linux fully, but I can't without quality magnification. If anyone can offer me advice on how to fix it, I'd appreciate the help.
Specs:
CPU: Intel i5-2500k @ 4.3 GHz (also tried at stock)
GPU: NVIDIA GTX 780 (with NVIDIA driver)
RAM: 8GB DDR3-1600
SSD: Crucial M4 64GB
Mouse: Logitech G600

I have pretty much the same specs. This bug may be related to this https://bugzilla.gnome.org/show_bug.cgi?id=719609 but it doesn't seem anyone has looked at it yet.
Seems to me like there are major issues with the proprietary nVidia driver and Gnome Shell.. I know the memory leak is terrible on my system, the gnome-shell process hit 1.9gb the other day after 2 days of uptime. I have to ALT+F2 and type "r" to restart the shell to bring the process back to normal, but it steadily climbs back up again.
Have you tried the Nouveau driver? From what I've read the memory leaks are less severe with other drivers and the magnification tool may work better. Maybe someone else using Gnome Shell + Nouveau can confirm this?
