Hi I do get this error with paged lists when scrolling to fast. It didn't happen with Version 3.0.0 But does atleast since 3.2.0.

Disabling animations seems to resolve this animation kind of. Not sure why or if thats pure luck while scrolling Disabled animations do not change it

Disableing placeholders fixed it for me but brings much other problems, like my views (horizontal viewpager oder vertical recyclerview) is moving randomly scrolling data is updated or inserted.

I have the same problem and the same error in another project. It seems a bug in Android I suppose as it happens randomly. In my case, it happens when I delete randomly items in the RecyclerView when placeholders set to true and hasStableIds set to true also. Never happened when placeholders set to false and hasStableIds set to false. Any idea how to solve this issue? Thanks

I have the same problem, it happens randomly and in some devices, my app in play store report this problem to Crashlytics 2 times. I hope it will be fixed.

Look like it's a bug from Android
