Description Snjezana Peco CLA 2014-02-10 16:07:43 EST 
The issue only happens on Linux GTK3.
I have tested Luna 4.4M5.

Steps to reproduce:

Try to run a Form editor that configures a header (pom.xml, Mylyn New Task editor, JBoss Tools Central, for instance).
You will get an error log as described in https://issues.jboss.org/browse/JBIDE-16501
The form heading widget is painted before configuring.
The issue doesn't happen when using Plug-in Manifest Editor 

Attached is a patch.

What's happening in GTK3?  Doesn't that make this an SWT bug?

I think the bug is caused by the way GTK3 fires paint events.
Not sure if it can be fixed in SWT.
I have created a simple fix.
