There has been some recent updates in the upstream bug [1,2] - too bad that Launchpad cannot track it.
>From January 3rd: "This is an issue with gtk version 3.20 and later. gtk has made some major changes in their theme handling in gtk 3.20 and applications need to change to adapt to those changes. This issue is reproducible in Ubuntu 18.04 and OEL 7.5 as the gtk version is >3.20 in both whereas in Ubuntu 16.04, the default version is 3.18 and works fine. Further investigation needs to be done on exactly what changes are required to make this work with gtk version >=3.20". >From last week: "Fix Request (11u, 8u) This issue solves GTK 3+ compatibility problems. Upstream patch contains fixes for 4 issues (JDK-8218469, JDK-8218470, JDK-8218472, JDK-8203627). It applies cleanly to 11u (and I see 11.0.4-oracle), and to 8u with reshuffling (and I see 8u221/222). Original tests (JSlider, JProgressBar, JScrollBar, FileChooserDemo) work fine after the patch, and looks wrong before the patch. 8u requires -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel -Djdk.gtk.version=3 to reproduce. The risk is low." The fix [3] was added to 11.0.4 (not yet release) so I will backport and test it for Bionic's and Cosmic's OpenJDK 11.
