HASS White Page on web reload

I have my dashboards reloading every 5 minutes due to some instable cameras. I have dark mode lovelace. Every reload the screen goes full bright white with HASS logo then loads my dashboard. How can i change this white splash screen. Its a very poor experience in the middle of the night.

Do you use a dark enabled theme, and set to “Auto”?
