Could people try the attached Java test program?
There is a bad redisplay problem for large (greater than around 1000
lines) text windows using a TextArea (or a Swing JTextPane).
I have the feeling it is specific to the Intel driver.
To test it, you need to have openjdk "java" installed and
in your path:
$ java -version
java version "1.6.0_0"
IcedTea6 1.4 (fedora-7.b12.fc10-i386) Runtime Environment (build
1.6.0_0-b12)
OpenJDK Server VM (build 10.0-b19, mixed mode)
Java is provided by java-1.6.0-openjdk-1.6.0.0-7.b12.fc10.i386.
However, the same problem occurs with jdk1.6.0 update 11
downloaded directly from Sun, as well as jdk 1.5.0_05.
To test it, put TextTest.java in a temporary directory,
cd to that directory, compile it, and run it:
$ javac TextTest.java
$ java TextTest
Now try scrolling back and forth a bit. What happens for me is that
the text lines will be over-written multiple times on top of each other.
The interesting thing is that only the first 700 lines
or so are garbled - the remaining lines are fine.
My guess is that there is some weird interaction between Java,
the Gtk peers, and the intel driver, since otherwise more people
would have reported this problem. Also, I have tried it on an
NVidia-based laptop, and well as with the vesa driver (iirc).
It would be helpful to get some data-points before I decide
whether to complain to Sun or to Intel or to Gnome!
Works fine in rawhide I can see the lines ( Line 1. to Line 3000 )
clearly, scroll up and down, no corruption nothing.
Shall reboot into F10 and try again.
NV driver.
$ java -version
java version "1.6.0_0"
IcedTea6 1.4 (fedora-8.b14.fc11-x86_64) Runtime Environment (build
1.6.0_0-b14)
OpenJDK 64-Bit Server VM (build 14.0-b08, mixed mode)

java-1.6.0-openjdk-devel-1.6.0.0-8.b14.fc11.x86_64 # Testers install
this package if you lack the java compiler
Note Tester
If you dont have the Java programming language compiler ( javac ) installed
install the java-1.6.0-openjdk-devel package..
