The AABalanceTest fails on systems with a somewhat small screen size, such as my Windows 10 laptop which I run in HiDPI mode (125% scaling) so that the effective screen size is 1280 x 720.

Here is the failure:

test.robot.test3d.AABalanceFlipTest > testAABalanceFlip FAILED
    junit.framework.AssertionFailedError: expected:rgba(255,255,255,255) but was:rgba(0,58,144,255)
        at test.robot.testharness.VisualTestBase.assertColorEquals(VisualTestBase.java:177)
        at test.robot.test3d.AABalanceFlipTest.lambda$testAABalanceFlip$1(AABalanceFlipTest.java:96)

This is a problem with the test. It is failing because it creates an 800x800 window and then samples it near the edges.
