It seems like a robot issue. These failures can also be observed without this change and with increased timeout (70000 ms).

>  The fix for [JDK-8170026](https://bugs.openjdk.java.net/browse/JDK-8170026) addressed this by skipping the tests that were sensitive to screen scale (14 of them). You either need to do something similar for `RegionBackgroundImageUITest`

Here also I made same change to skip the failing tests(listed in previous comment).
Please take a look.
