[Bug 682338] [NEW] GTK programs in Ubuntu 10.10 are sluggish over NX

[Launchpad Bug Tracker]

I use NX to connect to a work computer from home, over the Internet.  I
recently upgraded to Ubuntu 10.10, and I noticed that GTK programs
became very sluggish.

I currently have 1.10.0-1ubuntu3 of libcairo2 installed.  If I override
this with the Ubuntu 10.04 version of libcairo2, 1.8.10-2ubuntu1,
performance is restored.  I used LD_LIBRARY_PATH to run GTK programs
with the old libcairo2 package.

I'll attach a video demonstrating how much faster gedit is using the old
libcairo2 package.

Both my home and work computer run Ubuntu 10.10.

The work computer has these NX packages installed:
nxclient-3.4.0-7
nxnode-3.4.0-14
nxserver-3.4.0-14

The home computer only has the nxclient-3.4.0-7 package installed.

The ping times from my home computer to work computer are about 35ms.

I suspect this issue is related to, or a duplicate of, bug #595845.
