I could not find anything wrong with rendering or robot which otherwise could have caused issue in other systems and platforms but it's only failing in this CI system (but color profile setting is ok). As per [JDK-8266247](https://bugs.openjdk.java.net/browse/JDK-8266247) which also happens in same mc, some faulty video memory is doubted. Also, it's not happening everytime but intermittently so seeing all this, I have just relaxed color check a bit

I am not sure that the color profile or something like that can be the root cause, because the test does not check an exact RGB of the color, instead, it renders the image twice and then compares, so it is strange that the results are different.
