#Dialog backdrop filter no longer working after Home Assistant 2026.1 update

Hey everyone 👋

Quick question:
Since the Home Assistant 2026.1 update, the following setting in my theme.yaml no longer works for dialog windows:

ha-dialog-surface-backdrop-filter: "blur(10px)"

The blur / backdrop effect behind dialogs is no longer applied.

Has anyone else noticed this issue?

  • Is there a known alternative or workaround for dialog backdrops?
  • Was this changed or removed intentionally in 2026.1?
  • Or is this simply a bug?

Any help or pointers would be greatly appreciated

2026.1 introduced default for ha-dialog-scrim-backdrop-filter (existing var) to default to ha-dialog-scrim-backdrop-filter: brightness(68%) with the update for energy period selector so the calendar popup dialog gets this backdrop filter. So for backdrop filter this will take precedence over dialog surface backdrop filter.

So set ha-dialog-scrim-backdrop-filter: blur(10px) and you will be all set.

I tested it and it works perfectly
Thanks a lot for the explanation and help!

I just noticed the backdrop filter wasn't working on my popups. Same fix as mentioned above but I found it in the Styles doc. --vertical-align-dialog: center !important; was a good find along with the detailed Popups doc. (It's been a while since to poked around through the docs.)
