Bug#654565: Workspace switching very slow

[Philipp Klaus Krause]

Package: libvte9
Version: 1:0.28.1-1

I see exactly the same symptioms as in the following ubuntu bugreport:
https://bugs.launchpad.net/ubuntu/+source/vte/+bug/665548
Worksapce switching is very slow (multiple seconds) when terminal
windows are open. Switching time increases with the total area of
terminal Windows in the target workspace. It thus takes a very long
time, if there are multiple large terminal windows. It does not matter
itf the terminal windows are on top or behind other windows.

As with the bug reporter there, this is an Nvidia system using Nvidia's
non-free driver. It runs testing  (I have another system with an Intel
graphics card and unstable, with otherwise similar configuration, which
does not have this problem). I run xfce4.
