I think there has been a sync since the last release.
I believe the fix you want @geoeo are rather the ones that got merged in ensure data types match what PyQt expects by ijnek · Pull Request #118 · ros-visualization/rqt_bag · GitHub . These changes haven’t been backported to the humble branch (but should be) yet. Thanks for notifying because I forgot to inform @ivanpauno who reviewed and merged my PR. @ivanpauno Would you be able to do a backport to the humble branch please?
