This issue JDK-8276058 is broader than the cursor, related, this is why I would 
like to exclude it from it.

Sure, I have no comments about the changes related to stability, but there are 
suspicious cases like using tolerance.

I have mentioned that a few comments above, on aarch64 the cursor is always 
present on the screenshot, unlike x64. both systems are "similar".

BTW I have found that the built-in screencapture tool has the ability to take a 
screenshot with and w/o cursor, so probably there is a way to specify that as 
well via some public API. Or maybe it is so fast that the cursor flickering is 
invisible.
