Description:
When going from one main activity tab to another (ie. moving between the "Home", "MySQL Model", "Diagramme", "SQL Editor" and others), or when moving objects on the diagram editor, i experience frequent freezes, of variable duration from 10 seconds up to more than a minute.

As you can see below, nothing shows in the logfile. I have no other process- or memory-consuming tasks running at the same time, my load doesn't exceed 0.3 average, my memory doesn't go over 50% and my CPUs usage stays low.

This happends also on other machines, with similar or different hardware configuration, with less or more memory, all running Ubuntu 12.04 64bits. However, it works smoothly on previous versions of Ubuntu.

Here is the content of my logfile:

How to repeat:
Test with Ubuntu 12.04.1 LTS, 64bits.

Run MySQL Workbench, open a new model, create a diagram from the model, and open another panel (SQL Editor for example).

Try to navigate between panels, or moving objects around the diagram editor.

Thank you for the bug report. I can't repeat Ubuntu 12.04 64-bits as guess on VirtualBox.
