Thanks @gerard-ziemski for bringing out this important observation. It clearly indicates that there are some overflows which are undetected.

We have tested without Metal API validation enabled till now.
 
Now, I have fixed the JDK-8261620 bug that reported the crash on app launch with Metal API validation enabled.
More testing with “Metal API validation enabled” to follow..
