# Objective This `apply_deferred` doesn't seem to have any effect, pointlessly restricts parallelism and is responsible for a large number of system order ambiguities. Spotted as part of #7386. ## Solution Remove it. This is the *only* manual apply_deferred in the code base currently. ## Testing I've checked various UI examples and `split_screen`, and couldn't discern any difference. This looks like a remnant of a `(a, apply_deferred, b).chain()` pattern where `b` got removed, leaving us with a weird vestige. |
