Description
When "jtreg" regression test "test/jdk/java/awt/Color/AlphaColorTest.java" is run on VM with current desktop set to Unity, it passes but when is run on "ubuntu:GNOME" desktop (which is default in 18.04] it fails. The frame shown is white in colour ie red is 255 but the test expects frame's red color to be between 122-132.

java.lang.RuntimeException: Color is not as expected. Got java.awt.Color[r=255,g=255,b=255]

Comments
11u Fix Request: I would like to backport this patch to 11u, as it is on Oracle 11u backport list. The original patch does not apply cleanly. However, the conflict is minor, as quarantined test is not on 11u's problem list.

The file "WrongColorWithJDK13+23OnOracleLinux7.4.png" with a screenshot was attached to the bug. The screenshot demonstrates: - the regression test failure on Oracle Linux 7.4 x64 with JDK 13+23, which is the build without the fix for JDK-8214579 (resolved in JDK 13+24). - the dialog of the regression test with the wrong color which leads to the test failure and the terminal showing that the test passes and fails while being run with the same settings. The described above experiment with JDK 13+23 and following test runs show that the observed new intermittent test failure: "Color is not as expected. Got java.awt.Color[r=189,g=189,b=189]", is not new and was present in JDK 13 before integration of the fix JDK-8214579. - The intermittent test failure is also reproducible with: JDK 11+25, JDK 11+28.

I have tried to run the test "open/test/jdk/java/awt/Color/AlphaColorTest.java" with JDK 13 compiled from "jdk/jdk13" with/without this back out fix and the results are not so stable on my VirtualBox host with openSUSE Leap 15.0 OS (GNOME 3.26.2): > > 1.
