I have posted an R bug report at
http://bugs.r-project.org/cgi-bin/R/System-specific?id=14099
but according to the reply from Peter Dalgaard, this is an Ubuntu/Compiz specific problem. However, it's not totally Compiz-specific on my system since I also see (less severe) drawing problems on Metacity. If I View() a large matrix or data.frame, parts of it in the upper left corner are sometimes not drawn until I press a key or move the mouse. In some cases just the grid around the row names is affected, sometimes the row names themselves, sometimes even entries in the first columns. Steps to reproduce:

1. Make sure you're running Metacity.
2. Start R.
3. Run this in R and make sure not to move the mouse or press a button afterwards:
View(matrix(rnorm(1000000), ncol = 1000))
4. If the viewer window looks ok, close it and repeat from step 3.

I have attached another screenshot that shows the drawing problem in Metacity. Could somebody verify this? And if somebody has access to a non-Ubuntu Linux machine with R, could you check if the problem really is Ubuntu-specific?
