Original issue report and fix for OpenJDK 8 at
<a href="https://bugs.openjdk.java.net/browse/JDK-7105461">https://bugs.openjdk.java.net/browse/JDK-7105461</a>

Ubuntu has been using this patch since 10 Jul 2014.

Please advise on whether this patch is acceptable for IcedTea 2.5/2.6 or not.


>From LP: #1101348
=================
Activating the XRender-Pipeline in openjdk-7 for usage with netbeans creates
graphics corruption when scrolling.

For details please see the post on the xrender-dev mailinglist:

<a href="http://mail.openjdk.java.net/pipermail/xrender-dev/2013-January/000049.html">http://mail.openjdk.java.net/pipermail/xrender-dev/2013-January/000049.html</a>

The corruption can be seen in this screenshot:

Clemens Eisserer created a patch for openjdk-8, which he kindly pointed me to.
I took that patch and applied it to the openjdk-7 package and it works in
openjdk-7.

Currently I rebuild the openjdk Package on each new release and replace the
rt.jar - it would be nice if the patch could be integrated into the build
process.

I'll attach the patch I created (this is just a minor change from the original
version of Clemens Eisserer).
