Description
JDK9 b135, Ubuntu 16.04 (Unity) + HiDPI (scale = 2)

Please run the attached test code. Cannot expand the drop-down list of the tabs on the right side of the pane to navigate over the tabs.

The issue isn't reproducible with JDK8 on the same machine. Also isn't reproducible on non-HiDPI machine.

Cannot reproduce after JDK-8163496. I cannot seem to reproduce the alignment issue. I can reproduce Semyon's shadow issue under the drop down window. It seems to me that it only happens after I delete a tab though.

Cannot reproduce after JDK-8163496. But there is another issue. After any tab is closed the drop-down popup window becomes incorrectly aligned vertically (screenshot-1). This happens with both GTK2 and GTK3. Also, in the same scenario on GTK 3 artifacts sometimes appears arond the drop-down window (screen-shot). Looks like the shadow arond the drop-down is not composited well.
