I have moved the listener addition to the createUI method and combined the `getCenterPoint` calls to one `invokeAndWait` block at the start. However, this did not alleviate the need for the additional delays. Removing the delays caused failures on linux and macos. However, when the delays are re-added, the test passes again on all OS's through 3 sets of 100 repeats.
