This theme is using the Themes.update API after the window has been created to set the styles on the window. So I don't think we can 100% get rid of the flickering but we should be able to remove steps 4 and 5 from the list in comment #0.

(In reply to Jared Wein [:jaws] (please needinfo? me) from comment #1) > This theme is using the Themes.update API after the window has been created > to set the styles on the window. Is it a bug of the theme or a problem with the provided theme API that these styles set by the theme on the window can't be applied before first paint?
