Bumping the babel-plugin-styled-components to the last version 2.0.5 makes the performance from our tests decrease a lot making a unique test take at least 8 minutes to run and breaking it.

By now, our fix was reverted to the previous version 2.0.4 and our tests start to run normally again.

I'm also seeing a major perf regression of my website build after bumping to 2.0.5, 2.0.4 is fine. At runtime I also get a _styled is not defined error. From inspecting the code it seems like the styled component import is not added automatically.

I have the same problem here, but with the NextJS build.
It used to be 3 minutes (with 2.0.3) and now it takes over 20 minutes (2.0.5).

We're seeing build times increase so much that automated builds are timing out if we try to update from 2.0.3 to 2.0.5.

Thank you, I'm going to revert the last change. Is 2.0.4 as bad or just 2.0.5?

jordan-brough commented

Thanks. v2.0.6 seems to have fixed the issues we were seeing. 👍
