https://bugs.launchpad.net/ubuntu/+source/openjdk-7/+bug/1032936

Original issue report and fix for OpenJDK 8 at
https://bugs.openjdk.java.net/browse/JDK-7105461

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.

=================
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:

dev/2013-January/000049.html

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).

Ubuntu version:

Description: Ubuntu 12.10
Release: 12.10
