Found the issue, ugh
Noticed that when I do the following:
transaction.addToBackStack(null)
When adding a Fragment with ViewPager2, the above issue occurs, although, idk if it's becaugh of gcFragments() anymore.
As soon as I un-comment that line, the issue disappears.

Is the Sample application, to reproduce, move back really fast between page 2 -> 1 and vice versa (they are bottom buttons) a couple times.
Wait a couple seconds and page 1 (the black page) should turn white meaning the Fragment has been removed.
As soon as you comment line 40 on MainActivity, and attempt again, the error does not persist

Got to debug this now. Your sample indeed showcases an issue, so thanks for reporting and for the sample!
`transaction.addToBackStack(null)` adds the Fragment replacement transaction to the back stack, so you can go back to the previous state with the back button. Is that what you were looking to achieve? You said it works without it, which might help in the meantime.
Would you mind describing the use-case, so I better understand what you're trying to achieve? E.g. in the example, by switching between buttons 1 and 2 at some point you achieve multiple stack entries going back to the ViewPager2 Fragment.

Description
Issue found when `mCurrentItem` value is 1073742144. The result of `Math.abs(item - previousItem)` is 128 instead of 1, when the item we scroll to is 1073742145. This makes the ViewPager "pre-jump to nearby item for long jumps".
