[Bug 1514651] [NEW] KDE applications have graphical problems while running Java applications

[Agash85]

Public bug reported:

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.
