Since GTK+ 2.18 has introduced Client Side Windows, a couple of problems have appeared in Eclipse 3.5. One of them was resolved in GTK+ 2.18.0 (https://bugzilla.gnome.org/show_bug.cgi?id=589963), the other one needs fixing at the SWT-level (https://bugs.eclipse.org/bugs/show_bug.cgi?id=287307)
Since I don’t want to run Eclipse 3.6 milestones yet, I created a small diff between the two SWT versions (3.5.1 and 3.6) and isolated the necessary changes. I am currently running Eclipse 3.5.1 with this patch on my Ubuntu Karmic installation, and it fixes the problem.
Here is the diff:
