From 866ecd43a7772bfbec07f64173f89e2cd1c40a08 Mon Sep 17 00:00:00 2001 From: Elizabeth Thompson Date: Fri, 12 Sep 2025 18:57:18 -0700 Subject: [PATCH 1/6] fix(loading): improve loading screen theming for dark mode support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes white flash in dark mode and removes fallback "Loading..." text that was displaying in Times New Roman font. Changes: - Set themed background color on body using colorBgBase token - Supports both light (#ffffff) and dark mode backgrounds - Remove "Loading..." alt text from branded spinner image - Remove fallback "Loading..." text div entirely - Let React app handle loading state instead of HTML fallback This eliminates the white background flash when loading in dark mode and removes the unstyled "Loading..." text that appeared briefly. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- superset/templates/superset/spa.html | 12 ++++-------- 1 file changed, 4 insertions(+), 8 deletions(-) diff --git a/superset/templates/superset/spa.html b/superset/templates/superset/spa.html index 5352b16efaea..5971f845d383 100644 --- a/superset/templates/superset/spa.html +++ b/superset/templates/superset/spa.html @@ -69,11 +69,11 @@ {% endblock %} - + {% set tokens = theme_tokens | default({}) %} + {% block body %}
