Corrupted SWT Checkbox button on GTK none

Description Jiri Peterka CLA 2010-05-06 05:52:35 EDT 
Build Identifier: M20100211-1343

There are some corrupted widgets visible sometimes. See attached picture. Usual new Button(parent, SWT.CHECK); is used. I've see this problem on Fedora (GTK). Possibly bug in SWT-GTK.

Reproducible: Always

Steps to Reproduce:
1.Problem is for example on wizard page here 
http://anonsvn.jboss.org/repos/jbosstools/trunk/hibernatetools/plugins/org.hibernate.eclipse.jdt.ui/src/org/hibernate/eclipse/jdt/ui/internal/jpa/process/wizard/EntitiesList.java
2.see for "checkboxOptLock.setSelection(params.getEnableOptLock());"

Comment 2 Jiri Peterka CLA 2010-05-06 05:55:17 EDT 
Step 2 should be rather - Button checkboxOptLock = new Button(combolabel, SWT.CHECK);

Would it be possible for you to narrow down the problem to a simple SWT snippet? That should be helpful in diagnosing the problem more easily.

take a look at screenshot here:
https://jira.jboss.org/jira/browse/JBIDE-6027
https://jira.jboss.org/jira/browse/JBIDE-6022

the snippet is simplest:
Button checkboxOptLock = new Button(combolabel, SWT.CHECK);

and this shows some artifacts in Linux.
Comment 5 Vitali Yemialyanchyk CLA 2010-05-07 06:42:10 EDT 
checkboxOptLock has no text assignment, it has default value.

It's hard to determine the status of a bug with no steps to reproduce. The link from the description 404's. I'm going to close this for now, please feel free to re-open with a snippet reproducer if the issue persists.
