Thank you for taking the time to report this bug and helping to make Ubuntu better.
It's not clear what application you were trying to run. Could you please try running the java application by adding -Djdk.gtk.version=2 to the java command line and report back if that helps? This seems to be related to bug #1770278. That reports includes a couple screenshots, could you please take a look and report back if it is similar to what you are seeing? ** Changed in: openjdk-lts (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769405 Title: In GTK+ Look-And-Feel, Slider Controls Have No Visible Handle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-lts/+bug/1769405/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
