Content in cells multiplying ad infinitum

At a glance

A community member is experiencing an issue where their notebook cells keep concatenating after saving. The issue is caused by a bug with the RTC (Real-Time Collaboration) experimental flag being turned on, which can happen when there is a flaky connection. The recommended solution is to disable the RTC experimental flag in the User settings > Labs.

Hi everyone,

I'm having the following issue: I start working on a notebook, add some stuff in the cells and then after saving they keep concatenating one after the other non-stop. I turned off the ruff on save and that continued.

This is a bug with the RTC experimental flag on. This happens when its on and there is a flakey connection. I recommend disabling it in User settings > Labs.

Weird because I'm having this issue locally, but it fixed, thanks!
This also works for me...
We're disabling RTC globally in the next release given the number of issues it's caused. Excited to see how many people are trying out experimental flags though!
I understand why you guys are disabling it for now. I would too. You're not abandoning the feature though, are you? That's one of the big(ger) draws for our team to look to adopt marimo!
No, definitely not abandoning. It was just too unstable. Were you all already using it? What is your timeline for adopting marimo, if you haven’t already?
we're not using it already, but we're trying as hard as possible to get off of jupyter for all the reasons you articulated on TRPP:E230 :). In the meantime I'm working with a colleague to prototype some of our use cases using Marimo but the RTC feature isn't a deal breaker; it's just a really nice-to-have and now that we got a taste of it it's hard to imagine life without it. I'm glad you're not abandoning it! 😄
Yeah, RTC would be amazing for collaboration and live audio
We’ll get there! It’s just not ready to be released 🙂

we did another pass of bugfixes for RTC. For folks interested in using it, you can re-enable it in your marimo.toml or pyproject.toml

[tool.marimo.experimental]
