The Neomorphism theme brings a new fresh look to Discourse. It uses the neomorphic design system which involved paper-like realism to the UI.
Features:
Never Seen this one before,
is it happening with just this theme or some other theme as well, Also let me know what Discourse version are you using, we last tested on version 2.9.0 beta 3 and it worked fine.
The search menu and its logic was converted from (deprecated) widgets to glimmer components. The changes are currently hidden behind a group based feature flag, but we have the intention of making the glimmer search menu the new default in the near future. The changes will break any search overrides in your theme so I wanted to raise this to you prior to us making the switch.
I have tagged the theme as broken. As I explained above, the theme relies on the widget search menu which is deprecated and has now been removed from core completely. It will need to be refactored to account for the component based search menu.
