After some investigation it turned out that the increase in GDI object usage everytime there's a switch between pages (overview, models) results from a leak in the ToolStripTextBox control from the .NET framework (used as searchbox in the toolbar). Currently all the toolbars are recreated when the user switches between pages, which can be optimized. However this is a task not in the context of this bug report. Hence it can be closed.
