When NODE_ENV=production hydratation is broken

[julienfroidefond]

We use the 2.20.40 version. This issue happens with SSR styled components.

We are using : glamor.renderStatic(() => ReactDOMServer.renderToString(element)); for extracting the css/dom.

We have issues when NODE_ENV=production. This is a weird issue where randomly, the SSR

• doesn't render the style or sometimes,
• render a style which isn't the right one (and it is not coherent with the code ...)

When the hydratation happens, the style changes but is not the good one either and the change of state of parent doesn't do anything (no rerender when it should be)...

Do you have an idea where I can put a breakpoint to see why this is happening ? I am a little lost in the source of glamor...
