Description
Ubuntu 16.04 Linux (Unity) + HiDPI + JDK9 b135

Please run the attached test code and move a cursor over the checkboxes. The 1st time the tooltip "11111" occurs as expected. But when moving the cursor over the other checkboxes (or returning to the 1st), no tooltips are shown.

No such issue on a non-HiDPI machine with the same OS.

Not reproducible with JDK8

I cannot reproduce the issue after JDK-8163496. But sometimes I see a picture as shown on the attached screenshot. It is reproducible with GTK3 on Ubuntu 14.04 and 16.04 and never with GTK2.

Likely a duplicate of one of the other Hi-DPI Linux bugs.
