Repeating logs building due to progress spinner

Hello everyone!

I have the strangest issue. At our company we build our Gatsby project (Gatsby build) using a docker container and running it on Buildkite. Everything was completely fine until we decided to upgrade our version of Gatsby, this is when we started seeing HUGE logs (like 60+MBs) whereas before we had like 11KB. On closer inspection is seemed that Gatsby’s build process indicator (a little spinner that moves in place to indicate progress) was spitting out all of the logs on every tick, like when transitioning from ⠙ to ⠹

This spinner was there on the previous version and hadn’t changed.

We built the docker container locally but this didn’t seem to happen. Has anyone seen/dealt with a problem similar to this?

Worthwhile investigating:
