Hi All, Please review the following fix.
Bug: https://bugs.openjdk.java.net/browse/JDK-8214253 webrev http://cr.openjdk.java.net/~pbansal/8214253/webrev00/ Issue: >From gtk 3.20, gtk has changed the way themes and styles work for many >widgets. Due to which, jdk is not able to render some widgets properly >including JTooltip. The tooltip background looks transparent, but tooltip >background is of same color as background panel. gtk 3.20 release notes: https://developer.gnome.org/gtk3/stable/ch32s10.html Fix: This patch fixes rendering issues in JTooltip by using correct way to define styles. Testing: This fix can be verified by running SwingSet2 and using the tooltip. I have verified this on Ubuntu 16.04, 18.04, 18.10 and OEL 7.5. Regards, Pankaj Bansal
