@kennknowles Sorry my comment may have been unclear. I don't know the approach to fix this issue yet, rather I believe this issue was introduced by https://github.com/apache/beam/pull/17112. I could actually use some guidance by anyone with in depth knowledge of windowing. So far I'm working with the assumption that applying global windowing[1] to an input with non-global windowing results in a PCollection with mismatched WindowCoder[2]? I'm not able to reproduce this issue with a test yet, including a test that applies FixedWindows before running the `Write` transform.
