Title:
  KDE applications have graphical problems while running Java
  applications

Status in openjdk-7 package in Ubuntu:
  New

Bug description:
  System: Kubuntu 14.04 LTS
  Java: OpenJDK 7-JRE

  On October 28th was released an update for openjdk-7-jre.

  From /var/log/apt/
  $ zcat history.log.1.gz

  Start-Date: 2015-10-28  21:43:51
  Install: openjdk-7-jre-headless:amd64 (7u79-2.5.6-0ubuntu1.14.04.1, 7u85-2.6.1-5ubuntu0.14.04.1), openjdk-7-jre:amd64 (7u79-2.5.6-0ubuntu1.14.04.1, 7u85-2.6.1-5ubuntu0.14.04.1)

  Since this update KDE Plasma/KDE Apps have massive graphical problems,
  when at the same time is running a Java application.

  To reproduce the problem:
  1. Start a Java application, like JDownloader or TV-Browser
  2. Wait 1 or 2 minutes or sometimes: do an action in the Java application
  3. Open any KDE App, like Dolphin or Konsole/Terminal
  4. Let the magic begin and now any KDE App looks like the attachment. 

  This problem is a known issue at KDE-bugs
  (https://bugs.kde.org/show_bug.cgi?id=350976). Other distributions
  have this problem since august. In Kubuntu 14.04 since update on
  October 28th.

  Recommended solution is to install OpenJDK 8. Unfortunately in
  (K)Ubuntu 14.04 is only OpenJDK 7 available.

  This is a massive bug, because KDE Apps are unusable while Java is
  running.
