Comment 24 for bug 137401

I can confirm this problem, but I do not have XGL installed. I am using Ubuntu 7.10, nvidia 7800. Desktop effects are disabled. I have recorded a video to illustrate the difference:

Kate is on the right (obviously). It is essentially unusable, as are all of the other KDE apps I use.

Notes:
- I am using the a driver downloaded from nvidia manually, installed with Envy (I am new to this Envy thing). While I typically downloaded the nvidia drivers in Ubuntu 7.04 as well, I always installed them using their provided installer only. Unfortunately, the restricted nvidia driver provided in the repositories incorrectly detects and sets my 1920x1200 display to 1600x1200, even if I manually "force" it to use 1920x1200 in various ways, but that's another issue for another bug.
- Kate was quite fast in the time I've been using Ubuntu prior to 7.10, from 5.04 to 7.04.
- While Gtk-based applications seem to be generally slower than they were in 7.04 (I have no data to back that up), they all run at a usable speed, unlike Kate and other KDE applications.
