Hi,

I've looked a bit into this, and from what I can see it seems to be an upstream issue nextcloud/server#13556. It is of course made much worse using this theme, as the stylesheet is loaded on every page compared to other apps, where it is only when you use them. Looking through the different issues on this, I haven't been able to find a workaround/fix that I can implement on my side.

That's frustrating. But thanks for looking in to it. I'll close this issue.

Any ideas what needs to be fixed in the core server app to eliminate this? Seems like it's not recognizing resources outside of the webroot.

Better handling of symlinks for resources, seems to be what's needed. One part of the fix is made and waiting to be included into NC19, but it doesn't seem like there is a proper fix for the symlink part yet.
