Hi @rjbiccum, thanks for your post. That looks like the css is not getting loaded for some reason, either there is a connection issue to Webflow, or something is blocking the css.
As a next step, I would recommend to check that the browser is running the latest updates, and to see if there are any browser extensions loaded that might be conflicting with the Webflow browser code.
A good way to check if browser extensions are conflicting, is to open the browser in Incognito mode (in Chrome) or Private Window mode (in Safari) and reload the site in the designer.
It may be helpful to check to see if your local browser cache is disabled in the browser that is used with the designer.
This will help to force a re-download of latest page changes when those are made, as opposed to pulling from local browser cache.
See here as an example step by step to disable browser cache in Chrome: https://www.technipages.com/google-chrome-how-to-completely-disable-cache
And for Safari: https://www.technipages.com/apple-safari-completely-disable-cache
I hope this helps, I am not experiencing the trouble on this end.
