demo application

When starting Java's notepad demo application with the xrender backend enabled, it very frequently (about 80%) renderes the same icon for all toolbar entries.
At the second refresh (mouse hoover effect, window resizing) the correct icons are drawn.

This only happens with SNA enabled, using UXA the application pops up as expected.

Simply start the attached demo application with the following command line (java 7 is required):
java -Dsun.java2d.xrender=True -jar Notepad.jar

Forgot to mention, this happens on my i945GM based Laptop running Fedora16+updates.

Narrowed it down to overwriting the cached (temporary) upload buffer, but I haven't yet spotted how that can be.
