Subject: [Rd] Data viewer window not drawn properly with Compiz (PR#14099)
Message-ID: <20091201124010.D3F252831FED@mail.pubhealth.ku.dk>

Full_Name: Ulrich Keller
Version: 2.10.0
OS: Ubuntu Karmic i386
Submission from: (NULL) (158.64.77.254)


When Compiz is switched on in Ubuntu Karmic R's data editor is unusable. The
window contents are garbled from the start, and when scrolling through the data
using the arrow keys the contents of the editor window are not redrawn properly.
I have verified that the problem exists on two different machines with different
video hardware (Intel and ATI).

This might be an Ubuntu-specific problem (but I doubt it). I can't test this
since I don't have any non-Ubuntu machines.

Steps to reproduce:
1. Make sure Compiz is enabled.
2. Start R
3. Type:
View(matrix(rnorm(100), ncol = 5))
4. In the editor window that appears, use the arrow keys to scroll around.
Notice how the contents of the window get increasingly garbled.

I have already posted an Ubuntu bug report on Launchpad here:
https://bugs.launchpad.net/ubuntu/+source/r-base/+bug/472408

The Ubuntu bug report contains a screenshot of the broken editor window.
