Is there a bugzilla this fixes? If so, can you add a link?

There are still missing corner cases with cursor interaction and these fast plane updates on Picasso and Raven2 leading to endless PSTATE warnings for typical desktop usage depending on the userspace. This change should be reverted until these issues have been resolved.
