emacs, kile not refreshing lines when scolling

I am using emacs 23.1.1 on Ubuntu 9.04, kernel 2.6.28-17-generic. When I scroll up and down in a file, occasionally some of the lines are not refreshed properly. i.e. if a line with a lot of text is replaced with a line that has little text, some of the old text that used to be on the line remains (see attached screenshot,near the bottom).

I have the same problem in Kile, so it must not be a bug with either program directly (I think?). I do not have the problem with gedit.

For the record, the emacs message buffer contains the following on startup

Quote:

Invalid image size (see `max-image-size') [84 times]
Linum mode enabled
Invalid image size (see `max-image-size')
Linum mode disabled
Invalid image size (see `max-image-size') [17 times]
Buffer is read-only: #<buffer *GNU Emacs*>Invalid image size (see `max-image-size') [11 times]
Invalid image size (see `max-image-size') [83 times]
GNU Emacs 23.1.1 (i486-pc-linux-gnu, GTK+ Version 2.16.1) of 2009-09-17 on nannyberry, modified by Debian

Does anyone have any ideas? This is getting annoying!

After a bit of digging, I changed my appearance preferences to no effects,and this solved the problem.

This doesn't thrill me, but it is what I am going with for now.

It appears that the problem is either with the nvidia driver I'm using (180.44 with Quadro NVS 135M) or compiz or the mixture of the two.

Hope someone can shed some light on this for me.
