Hi,
While the image didn’t came through, I suspect you are reffering to this layout issue.
It is caused by a delayed styles script. The search styles are correctly enqueued, but I suspect you might be using some sort of a “performance enhancer” plugin, which captures and delays the style loading, causing the search style to break for until it’s styles are fully asynchronously loaded.
I strongly discourage delaying asset loading, as it may cause issues like this as the normal loading is disrupted. Unless you know how to extract critical styles to be pre-loaded to avoid these hickups, I don’t recommend enabling that feature.
Make sure to check your cache/performance enhancer plugin and disable delayed style loading, it will resolve the issue.
