Knime freezes after viewing a plot (since upgrade to 15.04)

[Igor]

Knime (an eclipse based program) https://www.knime.org/ was working perfectly in 14.04. Since my upgrade to 15.05 each time a try to visualize any kind of plot or table (that means a new window), the new window is created and the plot appears. But, from that point on, Knime entirely freezes

Hallo Igor
The problem you are reporting isn't related to Unity, but only to the app that freeze.
Can you please verify with the developer if it can work on 15.04 or is only designed for LTS relases ?
Best regards

Closing the bug. Unlikely unity is the cause for your problem.
